Očauš is a mountain in central Bosnia, the majority in the municipalities of Kotor Varoš and Teslić, at an altitude of 1,402 meters (Mihailovac peak).

However, it was the economic and political situation in Europe during the early 19th century plus the fact that the Spanish Crown re-issued the Royal Decree of Graces (Real Cédula de Gracias) which now allowed Europeans who were not of Spanish origin to immigrate to the island that contributed the most to the immigration of hundreds of German families to Puerto Rico in search of a better life.

Puerto Rico was ceded by Spain to the United States under the terms of the 1898 Treaty of Paris, which ended the Spanish–American War, and the U.S. established military bases there.

Many soldiers of German-American background stationed in the island upon encountering Puerto Ricans of German ancestry quickly made social contact with them.

As a result, Puerto Ricans fought in Germany during World War II and have served in U.S. military installations in said country since then.
