Outwardly, Oman shares many of the cultural characteristics of its Arab neighbours, particularly those in the Gulf Cooperation Council. Despite these similarities, important factors make Oman unique in the Middle East. These result as much from geography and history as from culture and economics. The relatively recent and artificial nature of the state in Oman makes it difficult to describe a national culture; however, sufficient cultural heterogeneity exists within its national boundaries to make Oman distinct from other Arab States of the Persian Gulf. Oman's cultural diversity is greater than that of its Arab neighbours, given its historical expansion to the Swahili Coast and the Indian Ocean.
