Modern Indian plays emerged in the late 19th and early 20th centuries, coinciding with India’s colonial era and the rise of nationalism. The thematic concerns of these plays were multifaceted, as they sought to engage with the changing political, social, and cultural landscape of India during this period. The key themes in modern Indian theatre reflected the quest for identity, social reform, and resistance to colonial oppression. These concerns were not only a mirror of India’s struggle for independence but also a response to the modernization and Westernization that were influencing Indian society at the time. 

The initial thematic concerns of modern Indian plays can be divided into several major categories:

### 1. Nationalism and Colonialism
One of the most prominent themes in the early stages of modern Indian theatre was the question of colonialism and its impact on Indian identity. The British colonial rule had left a deep mark on Indian society, and many playwrights sought to address the question of national identity, sovereignty, and the desire for freedom. These plays often portrayed the effects of colonialism on the Indian people, their culture, and their way of life. 

For example, in the early 20th century, playwrights like Rabindranath Tagore, who was not only a poet but also an important figure in the development of modern Indian theatre, used drama to explore the theme of Indian identity in the face of Western influence. His works like *Rakta Karabi* and *Chandalika* raised questions about the social and cultural issues that emerged under colonial rule, while also promoting ideas of self-reliance and spiritual renewal. Similarly, the nationalist themes were reflected in the plays of other writers like Sri Aurobindo and Lala Lajpat Rai, who emphasized the importance of self-awareness and self-respect as crucial elements of India's struggle for independence.

### 2. Social Reform and the Status of Women
