Anna afterward. At a ceremony before the Parlement of Paris on 13 September, the Polish delegation handed over the "certificate of election to the throne of Poland-Lithuania". Henry also gave up any claims to succession and he "recognized the principle of free election" under the Henrician Articles and the pacta conventa. It was not until January 1574 that Henry was to reach the borders of Poland. On 21 February, Henry's coronation was held in Kraków. In mid-June 1574, upon learning of the death of his brother Charles IX, Henry left Poland and headed back to France. Henry's absence provoked a constitutional crisis that the Parliament attempted to resolve by notifying Henry that his throne would be lost if he did not return from France by 12 May 1575. His failure to return caused Parliament to declare his throne vacant. The short reign of Henry at Wawel Castle in Poland was marked by a clash of cultures between the Polish and the French. The young king and his followers were astonished by several Polish practices and disappointed by the rural poverty and harsh climate of the country. The Poles, on the other hand, wondered if all Frenchmen were as concerned with their appearance as their new king appeared to be. In many aspects, Polish culture had a positive influence on France. At Wawel, the French were introduced to new technologies of septic facilities, in which litter (excrement) was taken outside the castle walls. On returning to France, Henry wanted to order the construction of such facilities at the Louvre and other palaces. Other inventions introduced to the French by the Polish included a bath with regulated hot and cold water, as well as dining forks. In 1578, Henry created the Order of the Holy Spirit to commemorate his becoming first King of Poland and later King of France on the Feast of Pentecost and gave it precedence over the earlier Order of St. Michael, which had lost much of its original prestige by being awarded too frequently and too readily.

French reign (1574–1589) Henry was crowned king of France on 13 February 1575 at Reims Cathedral. Although he was expected to produce an heir after he married the 21-year-old Louise of Lorraine on 14 February 1575, no issue resulted from their
