Baldwin of Boulogne is crowned the first King of Jerusalem in the Church of the Nativity in Bethlehem.

Baldwin I was the first count of Edessa from 1098 to 1100 and king of Jerusalem from 1100 to his death in 1118. He was the youngest son of Eustace II, Count of Boulogne, and Ida of Lorraine and married a Norman noblewoman, Godehilde of Tosny. He received the County of Verdun in 1096, but he soon joined the crusader army of his brother Godfrey of Bouillon and became one of the most successful commanders of the First Crusade.

The king or queen of Jerusalem was the supreme ruler of the Kingdom of Jerusalem, a Crusader state founded in Jerusalem by the Latin Catholic leaders of the First Crusade, when the city was conquered in 1099. Most of them were men, but there were also five queens regnant of Jerusalem, either reigning alone suo jure, or as co-rulers of husbands who reigned as kings of Jerusalem jure uxoris.

The Church of the Nativity, or Basilica of the Nativity, is a basilica located in Bethlehem, West Bank, Palestine. The grotto holds a prominent religious significance to Christians of various denominations as the birthplace of Jesus. The grotto is the oldest site continuously used as a place of worship in Christianity, and the basilica is the oldest major church in the Holy Land.
