The Musandam Peninsula (Arabic: جَزِيْرَة مُسَنْدَم \ رَأْس مُسَنْدَم, romanized: Jazīrat Musandam / Raʾs Musandam), locally known as Ruus Al Jibal (Arabic: رُؤُوْس ٱلْجِبَال, romanized: Ruʾūs al-Jibāl Capes of the Mountains),^[3] is a peninsula that forms the northeastern point of the Arabian Peninsula.

In the modern era, the occupation of the region continued. In the beginning, the Portuguese invasion arrived, which destroyed the region after it was a global navigation center at that time. Then a new force appeared, the Ya’rubids state, and expelled the Portuguese invasion of the Gulf and occupied the peninsula region. Then came British colonialism. After the withdrawal of British colonialism, the UAE was formed, but Ras Al Khaimah did not join the UAE at that time. In 1972 AD, the Emirate of Ras Al Khaimah joined the United Arab Emirates. Then the Emirati-Omani border has been officially settled.
