ABSTRACT The leadership of servants is a new research area linked to ethics, virtues, and morality.
As critics debate whether this new leadership theory is significantly distinct, viable, and valuable for organizational success, scholars are currently looking for publication outlets.
The objective of this research was to identify empirical studies that explored the theory of servant leadership by involving a sample population to evaluate and synthesize the mechanisms, results, and impacts of servant leadership.
Therefore, we were trying to provide an evidence-informed answer to how the ship's servant leader works and how can we apply it? To synthesize research in a systematic, transparent and reproducible way, we conducted a systhematic literature review (SLR), a methodology adopted from the medical sciences.
A disciplined screening process resulted in 39 appropriate studies of the final sample population.
The synthesis of these empirical studies revealed: .
there is no consensus on the definition of servant leadership.
the theory of servant leadership is being studied in a variety of contexts, cultures, and themes.
researchers use multiple measures to explore servant leadership, and .
servant leadership is a viable theory of leadership that helps organizations and enhances us.
This research helps to develop the leadership of servants.
Theory and exercise.
Furthermore, this research contributes to the methodology for conducting SLRs in the field of management, highlighting an efficient method for thematically mapping and holistic viewing of new research topics.
By offering suggestions for future research, we conclude.

INTRODUCTION
Leadership is one of the behavioral sciences' most comprehensively researched processes of social influence.
This is because all economic, political, and organic systems' success depends on these systems' leaders' effective and efficient guidance (Barrow 1.
A critical factor in understanding an organization's success, then, is studying its leaders.

Some studies have discussed the beneficial effects of servant leadership on organizational profits and employee satisfaction (DePree, 1989.

However, the conceptualization of servant leadership as a way of life rather than a management technique by Greenleaf .
may have slowed the acceptance of this leadership theory in academia, as scholars ask the question: if it is a way of life, how can it be empirically tested? Even the admitted servant leadership of Greenleaf is unorthodox and would be difficult to operate and apply, as " it is not meant to be a scholarly treatise or a how-to-do-it manual " (Greenleaf 1977.
The majority of research to date on servant leadership involves developing theoretical frameworks and establishing measurement tools to enable future scholars to use these tools in practice and as a tenable theory to explore servant leadership.
A limited amount of research has empirically examined this construct.
We sought to identify these empirical studies that investigated servant leadership by engaging a sample population in order to evaluate and synthesize its mechanisms, results, and impacts as an aid in advancing servant leadership theory.
There is currently no comprehensive summary of empirical studies exploring the theory of servant leadership in organizational environments .
, a systematic literature review (SLR)), which is a gap in existing literature.
We provide evidence that servant leadership is a tenable theory by exploring empirical studies investigating servant leadership theory in organizational contexts.
As a promising new field of research, servant leadership faces the challenges once addressed by early service marketing and sports management scholars whose new ideas and concepts were slowly adopted in the conservative academic culture (Shannon 1.
Similarly, for their work, servant leadership scholars have sought a range of publication outlets while confronting a debate on the distinction and significance for organizations and employees of this leadership Moreover, the acceleration of knowledge production in the field of management has resulted in a body of knowledge that is increasingly transdisciplinary, fragmented, and Avinash Pawar et.

interdependent on progress in the social sciences.
A literature review is a key tool for managing the diversity of knowledge for an academic investigation in management research.
however, a criticism of these reviews is that they are typically descriptive accounts of contributions of selected writers often arbitrarily chosen by the researcher for inclusion and that these reviews may lack a critical evaluation of included studies (Tranfield et al.
On the other hand, a SLR differs from traditional narrative reviews by adopting a replicable, scientific and transparent process aimed at mitigating bias through comprehensive literature searches and providing an audit trail of the findings.
A discussion of how to conduct an SLR, critically evaluate studies, and integrate the conclusions is a current management research gap.
We assess the current state of the field in servant leadership research in this SLR and synthesize divergent We also advance a rigorous methodology for conducting an SRL in management research in this SLR.
Therefore, the purpose of this study was to systematically examine and organize the current body of literature research that in a given organizational environment, either quantitatively or qualitatively explored servant leadership theory.
We included only empirical studies in this SRL that examined servant leadership in an organizational context and excluded studies focusing primarily on model development or testing measurement tools.
Previous reviews on the concept of servant leadership focused on: the identification of key features (Russell and Stone 2.
, the development of measurements (Barbuto and Wheeler 2.
, and the suggestion of a theoretical framework (Van Dierendonck 2.

SERVANT LEADERSHIP THEORY
Although servant leadership is a growing trend in the practice of private and non-profit organizations, there is still a lack of research in this area (Farling et al.

Many authors present narrative examples of how servant leadership is being used in organizations.
however, this is also the primary limitation of much of the servant leadership literature (Bowman 1997.

The servant-first paradigm has since motivated scholars and practitioners to explore the possibilities of this paradigm.
As of 1999, two research streams had emerged: conceptual (Spears, 1998.

, measurement (Page and Wong, 2000.

Notably absent are empirical studies exploring servant leadership theory in a given organizational setting.

third review also concludes with another conceptual model that identifies six key features of leadership: empowering and developing individuals, humility, authenticity, interpersonal acceptance, guidance and stewardship.
All of these reviews exemplify various interpretations of Greenleaf's writings using various terminologies.
all, however, include the fundamental mental dimension of servitude or the willingness to serve others.
These reviews emphasize the plurality of the theory of ser-vant leadership, allowing the researcher, student, or practitioner to ponder precisely the theory of servant leadership.
There is more than one kind of good theory, as DiMaggio .
pointed out .
Since the development of conceptual frameworks and measurement tools for servant leadership has been examined in previous reviews, the present review focuses only on empirical studies that have explored the theory of servant leadership in an organizational context.
As such, the current study is the first review to provide a synthesis of empirical studies conducted on the theory of servant leadership in organic settings, based on evidence in published peer-reviewed METHOD The SLR is often compared to traditional reviews of literature because systematic reviews are objective, replicable, systematic, comprehensive, and the method is reported in the same way as empirical research reporting (Weed 2.
The origin of SLRs is in the fields of medicine, health care and policy, where the best evidence has been used to make clinical and policy decisions (Cook et al.

Management SLRs are used to provide a specific area with transparency, clarity, accessibility and impartial, inclusive coverage (Thorpe et al.

Since our focus was to gain insight into the empirical study of the theory of servant leadership, studies with a primary focus on model development or testing of measurement tools were excluded.
The approach of this review included extensive searches of relevant databases in order to ensure that all literature on servant leadership was identified as far as possible while maintaining the focus on literature that is most relevant to research issues .

Searches for pub-led studies were carried out systematically, following the order of the above-mentioned databases.
Criteria for inclusion and Exclusion The initial search required studies that must: .
be published in a peer-reviewed journal.
be in the English language, and .
use the keyword " servant leadership.
" No restriction was placed on the year of publication.
The number of articles recovered from each database containing the keyword " servant leadership " was recorded.
Next, we examined whether any external duplicates were being searched from the current database and from the previous databases that were already searched.
The number of external duplicates was recorded, and then duplicated journal articles were deleted from the last searched database while keeping the total number of new articles found running.
Once all possible studies were identified, a second screening was conducted to evaluate eligibility for inclusion criteria, and then full-text papers were retrieved for those who met the inclusion criteria.
The inclusion criteria for the second screening required that the published peer-reviewed article meet all the following four specifications: .

and low .
Our classification for high to low-quality studies is described in Table 2, which was based on the three critical assessment tools listed above.
The results of these studies have been summarized and put into matrices.
Our SLR findings consist of a synthesis of the results for each study from all 39 empirical studies along with the quality assessment.
In addition, we evaluate the degree of supporting evidence for the-matic conclusions drawn from combining the findings of several studies.
RESULT AND DISCUSSION
Overall, this review highlights that the theory of servant leadership is being studied and tested across a range of contexts, cultures, disciplines, and themes.
11 qualitative studies, 27 quantitative studies, and one mixed-method study were included in our sample, all empirically evaluating the theory of servant leadership.
Therefore, this review shows that servant leadership is being studied both quantitatively and qualitatively, and with studies being conducted in 11 countries, the subject has an international appeal.
22 studies were classified as high, 12 as medium, and five as low quality in the quality evaluation.
Based on the synthesis of findings from each article, conclusive statements were made.

The following discussion of our findings is organized around the four central research questions.
How has Servant Leadership been defined? Servant Leadership Theory was introduced to readers by authors of empiric studies, citing one or all three of the following: Greenleaf .
Spears .
5, 1998, 2.
, and Laub .
In general, the authors described the servant-leader by quoting one of these three authors, not to mention several other authors, including, but not limited to: Barbuto and Wheeler .
Graham .
Ehrhart .
Liden et al.
Page and Wong .
, and Patterson .
Here, we discuss the three most-cited authors on the leadership of servants who have provided definitions.
Greenleaf .
0, 1972a, b, 1.
, the grandfather of servant leadership, was cited in 37 of the 39 empiric studies.
Most of the authors used part or all of Greenleaf's description of his original essay.
The Servant Leader .
It begins with the natural feeling that one wants to serve, to serve first.
Then a conscious choice brings one to aspire to lead.
That person is distinctly different from the leader first.
The difference manifests itself in the servant's careAifirst to make sure that other people's highest priority needs are being served.
The best test, and difficult to manage, is this: are those served growing up as individuals? Do they become healthier, wiser, freer, more autonomous, more likely to become servants while they are served? And what is the effect on society's least privileged? Will they benefit from it or at least not be further deprived of it? (Greenleaf 1970, cited in Greenleaf 1977, p.
Like Greenleaf himself, most authors in our sample defined servant leadership theory in a descriptive manner.
These descriptions usually include several scholarly works in the conceptual and measurement research streams and the reference to leading authors of organizational management.
Larry Spears was the second best-referred author to define servant leadership theory.
Like Greenleaf.
Spears gained his knowledge from practice, most of his works being non-empirical.
He served for 17 years as head of the Greenleaf Center, wrote more than 10 books on servant leadership, and established the Larry C.
Spears Center for Servant Leadership.

Spears .

identified 10 isthics of Greenleaf's servants' writings: listening, compassion, healing, awareness, persuasion, philosophy, conceptualization, foresight, stewardship, commitment to human growth, and community building.
Four of the qualitative studies in our sample used Spear's 10 characteristics to inform their analysis (Crippen 2004.
Crippen and Wallin 2008a, b.
Sturm 2.
Laub .
is the third most cited author in defining the servant leadership theory.
His Organizational Leadership Assessment (OLA) was the result of his dissertation.
The OLA assesses the health of the organization on the basis of the six key areas of an effective service-oriented organization by exploring the perceptions of top leaders, managers and supervisors, and the workforce.
however, it does not assess the leadership of the individual leaders (OLA Group 2.
Authors in our sample used Laub's definition, which refers to the practice of servant leadership as "the International Journal of Educational Administration.
Management, and Leadership Volume 1.
Number 2.
November 2020.
Page 63- 76 good of those led over the self-interest of the leader" .
9, p.
In addition, the authors would list and describe Laub's six key variables of effective servant-led organization: .
values peopleAibelief, service, and non-judgmental listening to others.
develops peopleAiprovides learning, growth, encouragement, and assertiveness.
builds a communityAidevelops strong collaborative and personal relationships.

OLA has been widely used in health organizations (OLA Grou.
and has been used in six quantitative studies in our sample (Herman 2010.

In summary, our results confirm Anderson's .
and Van Dierendonck's .
assessments that the servant's leadership theory remains under-defined, with no consensus on its definition or theoretical framework.
Scholars are still trying to articulate Greenleaf's conceptualization of servant leadership by using various definitions from multiple works.
Servant Leadership Theory Empirically Investigated in What Contexts? Our sample demonstrates the theory of servant leadership that is being studied across cultures, contexts, and a variety of research areas.
Overall, the sample consisted of studies that included four cross-cultural studies in 11 countries.

Similarly, as this review shows, there is still no agreement on a strategy to measure the theory of servant leadership.
CONCLUSION
This SLR demonstrates that the theory of servant leadership applies in a variety of cultures, contexts, and organizational environments.
Although Greenleaf first coined the philosophy in the 1970s, it took until 2004 to explore servant leadership in an empirical way.
No limitation was placed on the publication year of peer-reviewed journal articles by this SLR.
however, no empirical studies were found in all databases searched prior to 2004.
To date, the majority of servant leadership research is either attempting to define and model the theory conceptually or developing measurement tools to empirically test it.
Thus, one of the major criticisms of the theoretical construct, which is the difficulty of operationalizing its concepts and principles, is addressed by the majority of research on servant leadership.
From our SLR, several interesting directions for future research have emerged.
First, only 39 empirical studies that explored the theory of servant leadership in organic settings were identified by this SLR, highlighting the need for researchers to empirically examine the construction of servant leadership in a variety of organizational contexts.
Researchers could explore how to build a servant-led organization in the burgeoning field of entrepreneurship or, in the area of organic change, research could explore how to implement servant leadership in an established organization or during a merger or acquisition.
Second, there is a need to invest in the history of servant leadership development, such as the leader's personal attributes, the leader's background, and the history and trajectory of the organization.
