In 1920 a students strike broke out in protest against the new University Act which the students believed would only benefit the elite and perpetuate colonial rule. 'National Schools' sprang up across the country in protest against the colonial education system, and the strike came to be commemorated as 'National Day'. There were further strikes and anti-tax protests in the later 1920s led by the "Wunthanu athin"s. Prominent among the political activists were Buddhist monks ("hpongyi"), such as U Ottama and U Seinda in the Arakan who subsequently led an armed rebellion against the British and later the nationalist government after independence, and U Wisara, the first martyr of the movement to die after a protracted hunger strike in prison.
