From the conquest of Granada (1492) to the campaigns of the Great Captain in the kingdom of Naples (1495), three ordinances laid the foundations of the Spanish military administration. In 1503 the "Great Ordinance" reflected the adoption of the long pike and the distribution of pawns in specialized companies. In 1534 the first official tercio was created, that of Lombardy, and a year later it helped in the conquest of the Spanish Milanese. The Tercios of Naples and Sicily were created in 1536, thanks to the Genoa ordinance of Charles V.
