The passage discusses King Henry VIII's failed attempt to obtain an annulment of his marriage to Catherine of Aragon by 1529. It agrees that the diplomatic situation at the time, with the Pope heavily influenced by the Holy Roman Emperor Charles V who supported Catherine, made obtaining the annulment very difficult for Henry. However, it also notes that there were other reasons beyond just diplomacy, such as Henry's lack of powerful allies and the unpopularity of his advisor Cardinal Wolsey, which compounded the challenges and contributed to the failure to secure the annulment. While diplomacy played a big role, it was not solely responsible for Henry not obtaining the annulment as suggested by Source Three.
