What happened under umar and abu bakr leadership?

Under the leadership of Abu Bakr (632-634 CE) and Umar ibn al-Khattab (634-644 CE), the early Islamic state expanded significantly. Abu Bakr focused on consolidating the Muslim community after the Prophet Muhammad's death, leading the Ridda Wars to suppress rebellions. Umar continued this expansion, overseeing military campaigns that resulted in the rapid conquest of large territories, including parts of the Byzantine and Sassanian empires. Their leadership laid the foundation for the Islamic caliphate and significantly shaped the political and religious landscape of the region.
