Abraham Lincoln is a name that would be immediately recognizable to anyone who's had the opportunity to learn about American history. Showing unwavering leadership in times of adversity and genuine compassion for his people, the 16th president is still thought to be the epitome of what a great leader should be.

On Feb. 1, 1865, Lincoln approved a joint House and Senate resolution that later became the 13th Amendment to the U.S. Constitution. Feb. 1 was later officially declared National Freedom Day, with President Harry Truman signing the holiday proclamation into law in 1948.

To celebrate National Freedom Day this Monday, here are 15 of the many quotes Lincoln has imparted about freedom, equality and love for one's people and neighbor.
