first time in the city's Piazza San Sepolcro; here the future Fascist dictator launched his March on Rome on 28 October 1922. During the Second World War Milan large industrial and transport facilities suffered extensive damage from Allied bombings that often also hit residential districts. When Italy surrendered in 1943, German forces occupied and plundered most of northern Italy, fueling the birth of a massive resistance guerrilla movement. On April 29, 1945, the American 1st Armored Division was advancing on Milan but, before it arrived, the Italian resistance seized control of the city and executed Mussolini along with his mistress and several regime officers, that were later hanged and exposed in Piazzale Loreto, where one year before some resistance members had been executed. During the post-war economic boom, the reconstruction effort and the so-called Italian economic miracle attracted a large wave of internal migration (especially from rural areas of southern Italy) to Milan. The population grew from 1.3 million in 1951 to 1.7 million in 1967. During this period, Milan was rapidly rebuilt, with the construction of several innovative and modernist skyscrapers, such as the Torre Velasca and the Pirelli Tower, that soon became the symbols of this new era of prosperity. The economic prosperity was, however, overshadowed in the late 1960s and early 1970s during the so-called Years of Lead, when Milan witnessed an unprecedented wave of street violence, labour strikes and political terrorism. The apex of this period of turmoil occurred on 12 December 1969, when a bomb exploded at the National Agrarian Bank in Piazza Fontana, killing 17 people and injuring 88. In the 1980s, with the international success of Milanese houses (like Armani, Prada, Versace, Moschino and Dolce & Gabbana), Milan became one of the world's fashion capitals. The city saw also a marked rise in international tourism, notably from America and Japan, while the stock exchange increased its market capitalisation more than five-fold. This period led the mass media to nickname the metropolis "Milano da bere", literally "Milan to be drunk". However, in the 1990s, Milan was badly affected by Tangentopoli, a political scandal in which many politicians and businessmen were tried for corruption. The city was also affected by a severe financial crisis and a steady decline in textiles, automobile and steel production. Berlusconi's Milano 2 and Milano 3 projects were the most important housing projects of the 1980s and 1990s in Milan and
