This article is dedicated to the exploration and analysis of gender issues within Military Orders and the Crusades.

The aim of this study is to examine the intricate historical phenomenon of women's participation in these orders and the Crusades themselves. This approach allows for a more objective understanding of this phenomenon, offering a fresh perspective on historical events. Additionally, it highlights how different charters, such as the Augustinian or Benedictine, influenced attitudes towards women in various Orders, ranging from their complete exclusion to the assignment of significant roles within the Order's hierarchy. Furthermore, the article addresses the role of lay sisters, who were often wealthy and influential, thereby contributing to the overall functioning and structure of the Orders.

The relevance of the issues highlighted in this article is due to the fact that Kazakhstani researchers' current perspective on the gender issue of Crusades, particularly the role of hospital nurses, is based on analysis of Latin historical sources and modern works of Western scientists.

At the present stage of studying the activities of those orders in the circumstances of the Crusades, there are works on the study of women’s role in those Orders, since the gender issue, previously practically untouched, is today considered to be one of the most crucial in the study of this issue.

When working on the article, various scientific methods and approaches were used, not only of the historical discipline as such, but also of interdisciplinary methods.
