Final answer:
The Crusaders were promised salvation and forgiveness of sins for their service. They were also motivated by the chance to win land and a title.
Step-by-step explanation:
The Crusaders were promised various incentives in return for their service. One of the main incentives was salvation and forgiveness of sins, which was a powerful motivator for the devout Christians. The Church promised that by participating in the Crusades, the Crusaders would have the opportunity to atone for their sins and secure their place in heaven.
Additionally, the Crusaders were motivated by the chance to win land and a title. Many knights and nobles saw the Crusades as an opportunity to gain wealth, power, and social status. They also hoped to establish their own feudal domains in the conquered territories.
In summary, the promises of salvation and forgiveness of sins appealed to the religious motivations of the Crusaders, while the prospect of wealth, power, and land attracted those seeking economic and political benefits.
