The reason is that the second Republic of Venezuela was overthrown by reactionary forces in 1814. In the next few years, Bolí var, who fled abroad, summed up his experience and lessons, and thought that the South American continent under Spanish colonial rule was closely linked, and it was equally important to liberate his motherland and the whole continent. He conceived that all Americans were regarded as a whole, a enslaved nation. On this basis, he clearly put forward the slogan of "destroying the Spanish and defending the Americans" and said to the soldiers: For us, America is our motherland and Spain is our enemy. From this, he finally developed this idea into an idea of uniting America, preparing for defeating the colonists in the future and establishing a federal state of free association of Latin American people in America.
