Citing unwillingness to exploit the Fijian people, the colonial authorities did not permit Fijians to enlist. One Fijian of chiefly rank, a great-grandson of Cakobau, joined the French Foreign Legion and received France's highest military decoration, the Croix de Guerre. After going on to complete a law degree at Oxford University, this same chief returned to Fiji in 1921 as both a war hero and the country's first-ever university graduate. In the years that followed, Ratu Sir Lala Sukuna, as he was later known, established himself as the most powerful chief in Fiji and forged embryonic institutions for what would later become the modern Fijian nation.
