I assume you are looking for the answer "Mohammed and the Early Muslims", but Mohammed never declared war on Yethrib (the city which would become Medina). He settled there at the request of the Yethribis to resolve a dispute between two tribes. Mohammed and the Early Muslims did conquer Mecca, though, after difficult battles with Abu Sufyan and other Qoreishi Tribesmen. In more modern history, both the Ottoman Empire and Saudi Arabia conquered the territory of Hejaz in which Mecca and Medina are located, transferring those cities to those countries in the 1500s and 1920s respectively.
The Non-believers of Mecca (Makka) maltreated, insulted, and tortured the Muslims to such an extent that they had to migrate to Madina where they were offered refuge.
