The flag of Italy (bandiera d'Italia, often referred to in Italian as Il Tricolore) is a tricolour featuring three equally sized vertical pales of green, white and red, with the green at the hoist side. In its current form it has been in use since 19 June 1946 and was formally adopted on 1 January 1948. The colours chosen by the Republic were red and white, the colours of the flag of Milan and green, which was the colour of the uniform of the Milanese civic guard. Some have attributed particular values to the colours and a common interpretation is that the green represents the country's plains and the hills, white, the snow-capped Alps and red, blood spilt in the Wars of Italian Independence. A more religious interpretation is that the green represents hope, the white represents faith and the red represents charity; this references the three theological virtues
