The meeting of the Khilafat Committee in Uttar Pradesh was held in Allahabad.

Explanation:
The Khilafat Movement was a political campaign launched by Muslims in India during the early 20th century to support the caliphate of the Ottoman Empire and to protest against the unjust treatment of the Muslims in Turkey. The movement gained momentum after the end of World War I when the Ottoman Empire was dismembered and the caliphate was abolished by the Turkish nationalists.

The Khilafat Committee was formed to coordinate and lead the movement in various parts of India. It held meetings and organized protests to garner support for the cause. One of the significant meetings of the Khilafat Committee was held in Uttar Pradesh, specifically in Allahabad.

Allahabad, located in the northern part of Uttar Pradesh, was a major center of intellectual and political activity during the freedom struggle. It was chosen as the venue for the Khilafat Committee meeting due to its strategic location and its historical significance.

The meeting in Allahabad provided a platform for the leaders of the Khilafat Movement to discuss strategies, plan future actions, and mobilize public support. It was attended by prominent leaders such as Maulana Mohammad Ali, Maulana Shaukat Ali, and Mahatma Gandhi, who played a crucial role in shaping the movement.

The meeting in Allahabad was significant in terms of its impact on the Khilafat Movement and the broader freedom struggle. It helped to consolidate Muslim support for the movement and also fostered Hindu-Muslim unity, as leaders from both communities joined hands in the fight against British imperialism.

In conclusion, the meeting of the Khilafat Committee in Uttar Pradesh was held in Allahabad. This meeting played a crucial role in mobilizing support for the Khilafat Movement and fostering Hindu-Muslim unity in the struggle for independence.
