British princes Alfred Victor was in many ways the first British royal to tour major parts of the British empire and wider world. This chapter argues that his 1860s and 1870s journeys provided an important precedent for the more famous British princely tours that followed. With the partial exception of the tour of the Duke and Duchess of Cornwall and York in 1901, nineteenth- and early twentieth-century British royal tours borrowed generously, though not necessarily consciously, from Alfred's template. Alfred thus deserves to be remembered as the first major British royal tourist, from whom later princes borrowed 'something blue'. The 'royal naval arms race' accelerated in the early twentieth century. As nations vied to build bigger and more powerful warships, princes turned to these vessels for their overseas tours, which further enhanced their own status as naval officers.
