The Triumphal Procession (in German, "Triumphzug") or Triumphs of Maximilian is a monumental 16th-century series of woodcut prints by several artists, commissioned by the Holy Roman Emperor Maximilian I.
 The composite image was printed from over 130 separate wood blocks; a total of 139 are known.
 Approximately 54 m long, it is one of the largest prints ever produced.
 It was designed to be pasted to the walls in city halls or the palaces of princes to create a decorative frieze, an expression of the Emperor's power and magnificence: a pictorial form of the contemporaneous royal entry, which like many Renaissance entries looked back to the Roman triumph.
 Maximilian's papers show that he intended the procession to "grace the walls of council chambers and great halls of the empire, proclaiming for posterity the noble aims of their erstwhile ruler".
 It was one of several works of propaganda in literary and print form commissioned by Maximilian, who was always drastically short of money, and lacked the funds to actually stage such a ceremony, unlike his Habsburg descendants.
 It could also be bound as a book, and it is copies treated this way which have survived, as well as those from later reprints.

Don Agustín de Iturbide y Green, Prince of Iturbide (2 April 1863, in Mexico City, Mexico – 3 March 1925, in Washington, D.C.) was the grandson of Agustín de Iturbide, the first emperor of independent Mexico, and his consort Empress Ana María.
 He became the adopted son, along with his cousin Salvador de Itúrbide y de Marzán, of Mexico's only other royal heads of state—Emperor Maximilian I of Mexico and Empress Carlota of Mexico.
 After the death of Emperor Maximilian in 1867, he became the Head of the Imperial House of Mexico, but he had no children.
 His claims passed to Maria Josepha Sophia de Iturbide, the daughter of his cousin, Salvador.
Maximilian (Spanish: "Maximiliano"; born "Ferdinand Maximilian Joseph"; 6 July 1832 – 19 June 1867) was the only monarch of the Second Mexican Empire.
 He was a younger brother of the Austrian emperor Francis Joseph I.
 After a distinguished career in the Austrian Navy, he accepted an offer by Napoleon III of France to rule Mexico.
 France (along with the United Kingdom and Spain, who both withdrew the following year after negotiating agreements with Mexico's democratic government) had invaded Mexico in the winter of 1861, as part of the War of the French Intervention.
 Seeking to legitimize French rule in the Americas, Napoleon III invited Maximilian to establish a new Mexican monarchy for him.
 With the support of the French army, and a group of conservative Mexican monarchists hostile to the liberal administration of new Mexican President Benito Juárez, Maximilian traveled to Mexico.
 Once there, he declared himself Emperor of Mexico on 10 April 1864.
