King Olav V died from a heart attack on 17 January 1991, after battling illness during the previous year.
Harald V was proclaimed king and swore an oath in the Norwegian Parliament (Storting) to uphold the constitution, with Queen Sonja present. The new Queen appeared in the main chamber for the first time in 69 years.
“I solemnly swear to reign in the Kingdom of Norway in accordance with its Constitution and laws, so help me Almighty God.”
The new King adopted the motto, “We give our all for Norway”, which had been used by his father and grandfather.
The King and the Queen were consecrated in Nidaros Cathedral in Trondheim on 23 June 1991, in a traditional ceremony which dates back more than 1,000 years in Norway, and was previously carried out during the coronation of a new monarch.
However, King Olav V replaced the Coronation service with a consecration service in 1958. King Harald and Queen Sonja have continued this tradition with Bishop Finn Wagle presiding over the ceremony.
After the consecration, King Harald and Queen Sonja went on a ten-day tour of Southern Norway – a tradition that dates back to the Middle Ages. Later that year, they spent 22 days travelling to four northern counties.
King Harald and Queen Sonja visited Australia on an state visit for the first time, although they had been to Australia during the 1970s before their accession as Crown Prince and Princess.
He is the first reigning monarch to visit Antarctica – the Norwegian dependency Queen Maud Land – in 2015.
The King and the Queen also visit various counties in Norway, and use the Royal Yacht Norge whilst travelling along the Norwegian coast.
