Frederick I was succeeded by his son, Frederick William I (1713–1740), the "Soldier-King" obsessed with the army and achieving self-sufficiency for his country. The new king dismissed most of the artisans from his father's court and granted military officers precedence over court officials. Ambitious and intelligent young men began to enter the military instead of law and administration. Conscription among the peasantry was more firmly enforced, based on the Swedish model. Frederick William I wore his simple blue military uniform at court, a style henceforth imitated by the rest of the Prussian court and his royal successors. In Prussia, pigtails replaced the full-bottomed wigs common at most German courts.
