Diplomatic influence refers to the ability of a country or individual to persuade, shape, or control the decisions and behavior of other countries or actors through diplomatic means such as negotiation, dialogue, and alliances. It involves leveraging relationships, communication skills, and understanding of international relations to advance one's interests on the global stage.
Jerusalem was acquired from Muslim control through diplomatic means by the Crusaders, specifically during the reign of King Baldwin IV of Jerusalem. The most notable instance was the negotiation between Richard the Lionheart of England and Saladin during the Third Crusade, which led to the city remaining under Muslim control but allowing Christian pilgrims access. Ultimately, it was not until the 20th century, particularly during the 1948 Arab-Israeli War, that Jerusalem was captured by Israeli forces, but that was through military means rather than diplomacy.

Robert Gray."In the 1830's and 1840's most Americans were convinced that their nation was destined to occupy all the land from the Mississippi River to the Pacific Ocean.

Through diplomatic negotiation with Great Britain in 1846, the United States acquired the Oregon territory, a vast area of 285,000 square miles."
