2. Widespread spread of bourgeois democratic revolutionary ideas (ideological conditions)

3. Extensive establishment of revolutionary organizations (organizational conditions)

4. Sichuan Road Protection Movement (external conditions)

First, the objective conditions for revolution have been met.

Economically, the rapid development of national capitalism in the early 20th century became the material basis for the rise of bourgeois democratic revolution in China.

In terms of class strength, with the rapid development of capitalism, the national bourgeoisie began to grow and further expanded in number;

Ideologically, at the beginning of the 20th century, the idea of democratic revolution spread widely, and revolution gradually became the main ideological trend of society.

Organizationally, bourgeois revolutionary groups were widely established, and the establishment of the League made the bourgeois democratic revolution enter a new stage of unified leadership of political parties;

Politically, the proposal of the Three People's Principles gave the bourgeois revolutionaries a common platform for struggle and promoted the development of the revolutionary movement.

Second, the revolutionary situation is rising day by day. After the constitutional failure of the Qing court, it was further isolated and declined, and the revolutionary forces grew stronger and stronger in the struggle for rights and armed uprising.

Third, the time is ripe for revolution. The movement of protecting roads mobilized new troops in Hubei, and the Qing court ruled emptiness in Hubei, which provided a favorable opportunity for the outbreak of Wuchang Uprising.
