Who was the key figure opposing the Weimar Republic during the Kapp Putsch?

The key figure opposing the Weimar Republic during the Kapp Putsch was Wolfgang Kapp. He was a right-wing politician and nationalist who, along with the Freikorps, led the attempted coup in March 1920 aimed at overthrowing the Weimar government. Kapp and his supporters were disillusioned with the Weimar Republic, which they believed was weak and illegitimate. This coup was a significant challenge to the authority of the Weimar government, demonstrating the political instability it faced during its early years.

Kapp's actions highlighted the tensions in post-World War I Germany, where various factions, including extreme right-wing groups and leftist movements, vied for power. His attempt to seize control ultimately failed when workers called a general strike, bringing Berlin to a standstill and leading to Kapp's retreat. This pivotal moment underscores the fragility of the Weimar Republic and the challenges it faced from within, particularly from right-wing factions, which were embodied in Kapp's Putsch.
