José Julián Martí Pérez (January 28, 1853 – May 19, 1895) is a Cuban national hero and an important figure in Latin American literature. In his short life he was a poet, an essayist, a journalist, a revolutionary philosopher, a translator, a professor, a publisher, and a political theorist. He was also a part of the Cuban Freemasons. Through his writings and political activity, he became a symbol for Cuba's bid for independence against Spain in the 19th century, and is referred to as the "Apostle of Cuban Independence." He also wrote about the threat of Spanish and US expansionism into Cuba. From adolescence, he dedicated his life to the promotion of liberty, political independence for Cuba, and intellectual independence for all Spanish Americans; his death was used as a cry for Cuban independence from Spain by both the Cuban revolutionaries and those Cubans previously reluctant to start a revolt.

The Cuban coat of arms is the official heraldic symbol of Cuba. It consists of a shield, in front of a Fasces crowned by the Phrygian Cap, all supported by an oak branch on one side and a laurel wreath on the other. The coat of arms was created by Miguel Teurbe Tolón and was adopted on April 24, 1906. The shield is divided into three parts:
In the chief, a key charging a blue sea between two rocks, symbolizing Cuba’s geographical position between Florida and the Yucatán Peninsula. A bright rising sun in the background symbolizes the rising of the new republic. A key is a symbol of Cuba as Cuba is the key to the Americas.
On the left are the stripes of the flag of Cuba but turned so as they are bendwise. On the right is a common Cuban landscape, Royal Palm tree, a symbol of Cuba with mountains in the background.
