**Answer:**

The Satya Shodak Samaj, also known as the Truth-Seeking Society, was established in 1873 by Jotiba Phule in Maharashtra, India. Jotiba Phule was a social reformer and a prominent figure in the fight against caste-based discrimination and inequality.

**Background:**

During the 19th century, India was under British colonial rule, and the caste system was deeply entrenched in society. The caste system divided society into rigid hierarchical groups, with the Brahmins (priestly class) at the top and the untouchables at the bottom. The lower castes faced severe social discrimination, oppression, and denial of basic human rights.

**Purpose and Objectives of the Satya Shodak Samaj:**

The Satya Shodak Samaj aimed to challenge and dismantle the oppressive caste system and work towards social equality, justice, and upliftment of the marginalized sections of society. Some of the main objectives of the Samaj were:

1. **Annihilation of Caste:** The Samaj sought to abolish the caste system and promote equality among all individuals, irrespective of their birth-based social status.

2. **Education and Empowerment:** Jotiba Phule believed that education was crucial for the upliftment of the lower castes. The Samaj focused on providing education and empowerment to the oppressed and marginalized communities.

3. **Women's Rights:** The Samaj also emphasized women's rights and advocated for gender equality. Jotiba Phule and his wife, Savitribai Phule, were pioneers in the movement for women's education and empowerment.

4. **Social Reform:** The Satya Shodak Samaj actively worked towards eradicating social evils like child marriage, sati (widow immolation), and other discriminatory practices prevalent in society.

5. **Organizing Movements:** The Samaj organized public meetings, rallies, and campaigns to create awareness about the injustices faced by the lower castes and to mobilize public support for social reform.

**Impact and Legacy:**

The establishment of the Satya Shodak Samaj marked a significant milestone in India's social reform movement. It laid the foundation for the larger anti-caste movement and inspired future social reformers and leaders in their fight against caste-based discrimination.

Jotiba Phule's work and the Satya Shodak Samaj played a crucial role in challenging the oppressive caste system and advocating for social justice and equality. Their efforts paved the way for the larger Dalit movement and continue to inspire generations in the ongoing struggle for social reform and equality in India.
