Margrethe II of Denmark

Margrethe II is Queen of Denmark. Having reigned as Denmark's monarch for over 50 years, she is the world's only queen regnant and the longest-serving current female head of state. Margrethe is known for her strong archaeological passion and has participated in several excavations, including in Italy, Egypt, Denmark and South America. She shared this interest with her grandfather Gustaf VI Adolf of Sweden, with whom she spent some time unearthing artefacts near Etruria in 1962. As of 2023, Margrethe has, as sovereign, received 42 official state visits and she has undertaken 55 foreign state visits herself.
