The outcome of the First Round Table Conference was no significant outcome due to the absence of the Muslim League.

Background:
The Round Table Conferences were a series of conferences organized by the British government in London in the 1930s to discuss the future of India's political system. The First Round Table Conference was held from November 12, 1930, to January 19, 1931.

Objective:
The objective of the conference was to address the demands of various Indian political parties and communities and to find a way forward for the constitutional future of India.

Participants:
The conference was attended by representatives from various political parties including the Indian National Congress (INC), Hindu Mahasabha, and various other caste and religious groups. However, one notable absence was the Muslim League, which boycotted the conference due to its dissatisfaction with the Simon Commission Report.

Outcome:
Despite the participation of various political parties and communities, the First Round Table Conference did not achieve significant success. The main reason for this was the absence of the Muslim League, which was one of the major political parties representing the Muslim community in India.

Lack of Muslim League:
The absence of the Muslim League meant that the conference did not have the full representation of all major political parties and communities in India. This limited the effectiveness and legitimacy of the conference's decisions. The Muslim League's boycott also highlighted the growing communal tensions in India and the lack of consensus on key issues.

Impact:
As a result of the absence of the Muslim League, the First Round Table Conference failed to address the concerns and demands of the Muslim community in India. This further fueled the divide between the Hindu and Muslim communities and hindered the progress towards a unified political solution.

Subsequent Conferences:
The Second and Third Round Table Conferences were held in 1931 and 1932 respectively, with the aim of rectifying the shortcomings of the first conference. These subsequent conferences saw the participation of the Muslim League and addressed some of the demands of the Muslim community, leading to the adoption of the Communal Award.

In Conclusion:
The First Round Table Conference did not achieve significant success primarily due to the absence of the Muslim League. The lack of representation of all major political parties and communities limited the effectiveness of the conference and hindered progress towards finding a consensus on the future of India's political system.

The First Round Table Conference did not achieve significant success, primarily due to the absence of Congress representation and the lack of agreements.
