As a pianist, Mozart performed at many concerts and music academies, for which he had to build a repertoire; similarly, he was in need of educational repertoire for his students. Between 1782 and 1786, Mozart composed, in addition to piano sonatas and variations, fourteen new concertos for piano with orchestra. He was certainly no novice in this field, already having no less than ten piano concertos under his belt (not to mention his violin concertos and his first collection of concertos for wind instruments). As such, Mozart's Vienna period begins with a remarkable trio of piano concertos, K. 413, 414 and 415. Mozart undoubtedly wrote them for himself. His concert activity in Vienna was extraordinary, especially in the first years, where he met with success as both a soloist and as a composer. He therefore decided to publish this trio at his own expense (on a subscription basis), obviously with an eye towards having another source of income.
