Persia, known today as Iran, refers to a historical region and modern nation-state in Western Asia with a rich cultural heritage that dates back thousands of years. The term Persia was used in the West until 1935, when the government requested that the country be referred to as Iran, which means 'Land of the Aryans.' Understanding this transformation is crucial in the context of growing national identities among various ethnic groups in the region, especially as Arab, Turkish, and Iranian nationalism began to take shape in the late 19th and early 20th centuries.
