What caused tension between Han Chinese and Hui communities in Ningxia during the 19th and 20th centuries?

Tensions between the Han and Hui communities in Ningxia during the 19th and 20th centuries were rooted in the distinct cultural and social separateness maintained by Muslim settlers who migrated to the region.1

This social divide intensified in the mid-19th century when Ningxia became embroiled in a broader Muslim revolt across northwestern China. Throughout the 20th century, the region remained an arena of conflict, exacerbated by the influence of Muslim warlords—specifically the Ma clan of Hezhou—who controlled the area after 1911. During the period between World Wars I and II, the region became a strategic focal point for various political powers, including the Nationalist Party, the Japanese, and the Russians, further complicating local dynamics. While communist authorities later sought to gain minority support by promising cultural and political rights, the majority of the Hui population remained aligned with the Ma clan until the People’s Liberation Army secured a military victory in the region.1
