The vast bulk of the Royal family's wealth — totaling at least £18 billion ($21 billion) in land, property and investments — now passes along a well-trodden, centuries-old path to the new monarch, King Charles, and his heir. The line of succession makes Prince William, now the first in line to the British throne, a much wealthier man. The future king inherits the private Duchy of Cornwall estate from his father. The duchy owns a sprawling portfolio of land and property covering almost 140,000 acres, most of it in southwest England. 📷: Ian Forsyth/Getty Images
