The Republic of Florence, which came into being in 1494, decided to create an assembly hall for their most important political committee, the "High Council", which was suited to the requirements and pretensions of the new republic. The majority of the construction work on the Sala del Gran Consiglio in the Florentine Palazzo Vecchio had been completed shortly before 1500. The pictorial program was to include two large wall paintings intended to express the self confidence of the new republic. It was planned that two important victories from recent Florentine history should be depicted: the Battle of Anghiari and the Battle of Cascina. The choice of artist had to measure up to the importance of the commission, and the decision was made in favour of two of the most highly esteemed Florentine artists of the age, Leonardo da Vinci and the young Michelangelo.

Neither of the two artists completed his works and we only know of their projects indirectly by their being mentioned in documents, or in the form of copies or sketches that have been associated with the project.
