Which people dwelled in lands peripheral to the byzantine and sasanian empires at the time islam arose?

The Arabs Muslims

Explanation:

Arabs Muslims were the ones who started conquering the neighbor’s territories; and within it, were the Byzantine and the Sasanian empires. The Arab Muslim forces took advantage that these territories were weakened by their never-ending fighting with each other. When they conquered the Byzantine and Sasanian territory they started to expand and conquer beyond those lands. The reasons of conquering these lands were majorly political and religious.  

answer: secession

secession, as it applies to the outbreak of the american civil war, comprises the series of events that began on december 20, 1860, and extended through june 8 of the next year when eleven states in the lower and upper south severed their ties with the union. the first seven seceding states of the lower south set up a provisional government at montgomery, alabama. after hostilities began at fort sumter in charleston harbor on april 12, 1861, the border states of virginia, arkansas, tennessee, and north carolina joined the new government, which then moved its capital to richmond, virginia. the union was thus divided approximately on geographic lines. twenty-one northern and border states retained the style and title of the united states, while the eleven slave states adopted the nomenclature of the confederate states of america.
