Abraham Lincoln
Abraham Lincoln valued saving the union from secessionists pressures more than ending slavery. His proclamation against slavery, in the form of emancipation clause was mainly aimed at weakening the confederate army, rather than freeing them.
The statement that [after the peasants carry out their revolt, Martin Luther sympathizes with them and joins their cause] is false.
It was expected that Martin Luther would support the Peasant War, yet he did not because he was not a revolutionary person and truth be told, he did not like peasants.
