Dario Fo (Italian pronunciation: ['da:rjo 'fo]; 24 March 1926 - 13 October 2016) was an Italian actor-playwright, comedian, singer, theatre director, stage designer, songwriter, painter, political campaigner for the Italian left-wing and the recipient of the 1997 Nobel Prize in Literature. In his time he was "arguably the most widely performed contemporary playwright in world theatre". Much of his dramatic work depends on improvisation and comprises the recovery of "illegitimate" forms of theatre, such as those performed by giullari (medieval strolling players) and, more famously, the ancient Italian style of commedia dell'arte. His plays have been translated into 30 languages and performed across the world, including in Argentina, Chile, Iran, the Netherlands, Poland, Romania, South Africa, South Korea, Spain, Sri Lanka  Sweden, the UK and Yugoslavia.
In 2001, Fo became Satrap of the College de 'Pataphysique. In 2004, Forza Italia senator Marcello Dell'Utri, on trial at the time for money laundering, sued Fo over references to him in his latest play. Fo was disgusted: "I have been doing satire for 40 years. It is paradox. It is grotesque." The play, titled The Two-Headed Anomaly and first performed in 2003, also poked fun at the shortness of then prime minister Silvio Berlusconi, had him strapped to a chair and given electric shock treatment and portrayed Vladimir Putin being shot dead by Chechen rebels while visiting Berlusconi's luxury villa in Sicily. The title refers to the subsequent transplanting of Putin's brain into Berlusconi's head, and the play was performed amid debate over Berlusconi's business and political interests and media censorship, with RAI having barred Italian satirists Sabina Guzzanti and Paolo Rossi from its television channels. Fo spoke of receiving threats from politicians if he performed it.  In 2005, Fo revealed plans to run for Mayor of Milan, the most economically important city in Italy, the following year. He said it was part of his ongoing fight to rid Milan of Berlusconi's political colleague Gabriele Albertini, the incumbent mayor. Ostracised by Italian television (both state--RAI having shunted his latest show off to a graveyard slot--and commercial--three quarters owned by Fo's long-time adversary Berlusconi), Fo instead elected to campaign on stage. Under the slogan "I am not a moderate", he opposed the centre-right administration's plans to demolish parts of the city centre and vowed to chase out those "money-grabbing bastards who have run this city for decades." Securing 23.4% of the vote in the primary election of centre-left The Union in January 2006, he was ultimately unsuccessful, finishing second to Milan's former police chief Bruno Ferrante.  Throughout the early 21st century until his death in 2016, Fo remained an active participant and campaigner on various political, social and cultural issues. He questioned the official accounts of the September 11 attacks and the collapse of the World Trade Center buildings in the film, Zero: An Investigation into 9/11. In 2008, he was among the signatories of an open letter to la Repubblica which called on the state to protect Roberto Saviano, whose life was under threat after exposing the clandestine activities of the Camorra in his 2006 book Gomorrah. Ahead of the 2013 Italian general election, Fo explained that the most recent targets of his satire included: "The banks mostly, and the big entrepreneurs. All those who hold the reins 'the show within a show', i.e. those who - through the media, television and in other ways - make every effort to ensure that the people accept the conditions they find themselves in."

What were some notable works during this period?

In 2001, Fo became Satrap of the College de 'Pataphysique.



Answer the question at the end by quoting:

Jan Zizka z Trocnova a Kalicha (Czech pronunciation: ['jan 'ZISka] ( listen); German: Johann Ziska; English: John Zizka of Trocnov and the Chalice) was a Czech general, a contemporary and follower of Jan Hus, Hussite military leader, and later also a Radical Hussite who led the Taborites. Zizka is held to be one of the most renowned military leaders by many historians and today he is widely considered a Czech national hero. He was born in the small village of Trocnov (now part of Borovany) in the Kingdom of Bohemia into an aristocratic family.
Zizka helped develop tactics of using wagon forts, called vozova hradba in Czech or Wagenburg by the Germans, as mobile fortifications. When the Hussite army faced a numerically superior opponent they prepared carts for the battle by forming them into squares or circles. The carts were joined wheel to wheel by chains and positioned aslant, with their corners attached to each other, so that horses could be harnessed to them quickly, if necessary. In front of this wall of carts a ditch was dug by camp followers. The crew of each cart consisted of 16-22 soldiers: 4-8 crossbowmen, 2 handgunners, 6-8 soldiers equipped with pikes or flails (the flail was the Hussite "national weapon"), 2 shield carriers and 2 drivers.  The Hussites' battle consisted of two stages, the first defensive, the second an offensive counterattack. In the first stage the army placed the carts near the enemy army and by means of artillery fire provoked the enemy into battle. The artillery would usually inflict heavy casualties at close range.  In order to avoid more losses, the enemy knights finally attacked. Then the infantry hidden behind the carts used firearms and crossbows to ward off the attack, weakening the enemy. The shooters aimed first at the horses, depriving the cavalry of its main advantage. Many of the knights died as their horses were shot and they fell.  As soon as the enemy's morale was lowered, the second stage, an offensive counterattack, began. The infantry and the cavalry burst out from behind the carts striking violently at the enemy, mostly from the flanks. While fighting on the flanks and being shelled from the carts the enemy was not able to put up much resistance. They were forced to withdraw, leaving behind dismounted knights in heavy armor who were unable to escape the battlefield. The enemy armies suffered heavy losses and the Hussites soon had the reputation of not taking captives.

Was there ever a successful defense against Wagenburg tactics?
