paragraph_text: Giovanni di Bicci de' Medici was born in Florence, Italy. He was the son of Averardo de' Medici and Jacopa Spini. His father, Averardo died in 1363 with a respectable amount of wealth. This inheritance was divided among Giovanni and his four brothers, leaving Giovanni with very little. However, his uncle, Vieri de’ Medici, was still a prominent banker in Florence. Vieri helped Giovanni begin his career in the Florentine banking system. He worked his way up through the ranks, eventually becoming a junior partner in the branch located in Rome. Vieri de’ Medici retired in 1393 leaving the bank in the hands of Giovanni. From this point the Medici bank grew vastly and quickly. This growth culminated with the acquisition as the Chief Papal Banker, which meant that the Medici Bank now handled the accounts of the Church. The Medici family bank, which he founded in 1397, became his main commercial interest. The Medici bank under Giovanni had branches throughout the northern Italian city-states and beyond, and constituted an early "multi-national" company.
