You can place items in "order" with ordinal numbers. For instance, il primo is the first course on a menu and il secondo is the second course. Vittorio Emanuele III, who ruled the unified Italian nation from 1900 to 1946, was the third king with that name. Pope Paul V (1605-1621) was the fifth pope with the name Paul. When used with the numerical succession of kings, popes, and emperors, the ordinal numbers are capitalized:

Vittorio Emanuele Secondo (Vittorio Emanuele II)
Leone Nono (Leone IX)
Carlo Quinto (Carlo V)
diciottesimo secolo (eighteenth century)

Notice the regularity of ordinal numbers beginning with undicesimo—the suffix -esimo is added to the cardinal numbers by dropping the final vowel of the cardinal number. The one exception includes numbers ending in -tré. Those numbers drop their accent and are unchanged when -esimo is added. Since Italian ordinal numbers function as adjectives, they must agree in gender and number with the nouns they modify: primo, prima, primi, prime.
