Yes, there have been instances in history where black people have participated in colonization and expansion of empires. For example, the ancient Nubian Kingdom of Kush, located in present-day Sudan, expanded its territory and exerted influence over neighboring regions. Additionally, the Mali Empire, led by Mansa Musa, expanded its territory and exerted control over various regions in West Africa. It's important to recognize that colonization and expansion of empires have been carried out by various groups throughout history, and it's not limited to any one race or ethnicity. **

Saudi Arabia was never colonized for several reasons. Firstly, its harsh desert environment made it difficult for foreign powers to establish and maintain control over the region. Additionally, the strong sense of national identity and unity among the Saudi people made it challenging for external powers to impose their rule. Furthermore, the strategic importance of Saudi Arabia as the birthplace of Islam and its control over the holy cities of Mecca and Medina made it a sensitive and potentially volatile region for foreign powers to intervene in. Finally, the discovery of oil in the 20th century further solidified Saudi Arabia's independence and allowed it to exert significant influence on the global stage. **
