paragraph_text: Accession
  
  On 4 March 1998, Prince Henri was appointed as lieutenant representative by his father, Grand Duke Jean, meaning that he assumed most of his father's constitutional powers. On 7 October 2000, immediately following the abdication of his father, Henri acceded as Grand Duke of Luxembourg and took the constitutional oath before the Chamber of Deputies later that day. He became Henri I even though Luxembourg had seven monarchs named Henri prior to 1815.
