Why Did The Meccans Change Over Time

Relations with Mecca deteriorate to the point of pitched battles between the two sides, with Muhammad leading his troops in the field. But in the end it is his diplomacy which wins the day. He persuades the Meccans to allow his followers back into the city, in 629, to make a pilgrimage to the Ka'ba and the Black Stone.On this first Muslim pilgrimage to Mecca, Muhammad's followers impress the local citizens both by their show of strength and by their self-control, departing peacefully after the agreed three days. But the following year the Meccans break a truce, provoking the Muslims to march on the city.
