While the Muslims lived in Mecca, the Muslims adamantly demanded that the population abandon their henotheistic and polytheistic religions and openly threatened to destroy their idols as God had told him to do. Understandably, this angered the Meccans greatly because their religions were special to them and they took to violently beating Mohammed and the Muslims to prevent them from destroying their sacred objects.
Once Mohammed and the Muslims left Mecca, Meccans no longer feared these negative outcomes and had little reason to continue to care about a small minority like the Muslims. However, while in Medina, Mohammed coordinated numerous raids on caravan shipments that were lightly armed and not antagonistic. At the time, Mohammed and the Muslims needed supplies in Medina and did not have the funds to buy such supplies on the open market. As a result, he resorted to violence to achieve his objectives. This persistent action (of violently attacking merchants trafficking through Arabia) caught the attention of the Meccans whose commerce he was ruining. This resulted in the Ghawazat (غوزات) or Skirmishes between Meccans and Medinans.
In 622 the local rulers of Mecca forced Muhammad and his small band of followers to leave the city of Mecca.

They did not attack Mecca. When the number of people who embraced Islam in Arabia reached to a hign level, Muhammad was commanded by God to take Mecca back. It always belonged to the One God of Abraham; so Muhammad took it back and clensed it of idols.
They conquered Makka and the holy Propher (MPBUH) announced general amnesty. He forgave even the enemies who had tortured him and his followers.
When Muhammad arrived in Mecca, he came for the sole purpose of cleansing it, in other words; to conquer it. When he did so, no-one put up a fight and, even the leaders submitted to his army. They knew now that they could no longer pose a threat to the ever-growing band of Muhammad's followers and that resisting would lead to unnecessary bloodshed, for a lost cause. Thus, having militarily defeated the Meccans, the Muslims took over Mecca and, due to Muhammad being their leader, it was only fitting for him to be handed over the control.
The hegira is the migration and journey of the Islamic prophet Muhammad and his followers from Mecca to Medina in June 622 CE.
Simply because they rejected His message, this happened to many Messengers before Muhammad PBUH.
