What is the last king of the cross?

Here's information about the last king of the Crusader Kingdom of Jerusalem:

Hugh III (also known as Hugh I of Cyprus) was effectively the last King of Jerusalem to actually reside in the Kingdom, though he claimed the title until his death. After him, the title became largely symbolic and contested among European rulers.

• He was born circa 1235 and died in 1284.

• He reigned as King of Cyprus from 1267 and claimed the title King of Jerusalem from 1268.

• His claim to the Jerusalem throne was based on being the senior descendant of the House of Lusignan.

• After the death of Conradin in 1268, the line of Hohenstaufen, the hereditary kings of Jerusalem, became extinct, making Hugh the heir.

• However, another claimant, <a href="https://www.wikiwhat.page/kavramlar/Charles%20of%20Anjou">Charles of Anjou</a>, challenged his claim and managed to gain control of Acre.

• Although Hugh III was crowned king in Tyre, <a href="https://www.wikiwhat.page/kavramlar/Acre">Acre</a>, the de facto capital, remained under Charles's control.

• Hugh's reign was marked by internal conflicts and external threats, especially from the <a href="https://www.wikiwhat.page/kavramlar/Mamluk%20Sultanate">Mamluk Sultanate</a>.

• After Hugh III, the Kingdom of Jerusalem continued to exist in name only, primarily based in Cyprus. The title passed to his son <a href="https://www.wikiwhat.page/kavramlar/John%20I%20of%20Cyprus">John I of Cyprus</a> after his death.
