Pieter Willem Botha, DMS (Afrikaans pronunciation: ['pit@r 'v@l@m 'bU@ta]; 12 January 1916 - 31 October 2006), commonly known as "P. W." and Die Groot Krokodil (Afrikaans for "The Big Crocodile"), was the leader of South Africa from 1978 to 1989, serving as the last Prime Minister from 1978 to 1984 and the first executive State President from 1984 to 1989. First elected to Parliament in 1948, Botha was an outspoken opponent of majority rule and international communism. However, his administration did make concessions towards political reform, whereas internal unrest saw widespread human rights abuses at the hands of the government. Botha resigned the leadership of the ruling National Party in February 1989 after suffering a stroke and six months later was coerced to leave the presidency as well.
In superficial ways, Botha's application of the apartheid system was less repressive than that of his predecessors. He legalised interracial marriage and miscegenation, both completely banned since the late 1940s. The constitutional prohibition on multiracial political parties was lifted. He also relaxed the Group Areas Act, which barred non-whites from living in certain areas. In 1988, a new law created "Open Group Areas" or racially mixed neighborhoods. But these neighborhoods had to receive a Government permit, and had to have the support of the local Whites immediately concerned, and had to be a high class neighborhood in the major cities typically in order to receive the permit. In 1983, the above constitutional reforms granted limited political rights to Coloureds and Indians. Botha also became the first South African government leader to authorise contacts with Nelson Mandela, the imprisoned leader of the African National Congress. However, in the face of rising discontent and violence, Botha refused to cede political power to blacks and imposed greater security measures against anti-apartheid activists. Botha also refused to negotiate with the ANC. In 1985, Botha delivered the Rubicon speech which was a policy address in which he refused to give in to demands by the black population, including the release of Mandela. Botha's defiance of international opinion further isolated South Africa, leading to economic sanctions and a rapid decline in the value of the rand. The following year, when the US introduced the Comprehensive Anti-Apartheid Act, Botha declared a nationwide state of emergency. He is famously quoted during this time as saying, "This uprising will bring out the beast in us". As economic and diplomatic actions against South Africa increased, civil unrest spread amongst the black population, supported by the ANC and neighbouring black-majority governments. On 16 May 1986, Botha publicly warned neighbouring states against engaging in "unsolicited interference" in South Africa's affairs. Four days later, Botha ordered air strikes against selected targets in Lusaka, Harare, and Gaborone, including the offices of exiled ANC activists. Botha charged that these raids were just a "first installment" and showed that "South Africa has the capacity and the will to break the [African National Congress]." In spite of the concessions made by Botha, the apartheid years under his leadership were by far the most brutal. Thousands were detained without trial during Botha's presidency, while others were tortured and killed. The Truth and Reconciliation Commission found Botha responsible for gross violations of human rights. He was also found to have directly authorised 'unlawful activity which included killing.' However, Botha refused to apologise for apartheid. In a 2006 interview to mark his 90th birthday, he suggested that he had no regrets about the way he had run the country. He denied, however, that he had ever considered black South Africans to be in any way inferior to whites, but conceded that "some" whites did hold that view. He also claimed that the apartheid policies were inherited from the British colonial administration in the Cape and Natal Province, implying that he considered them something he and his government had followed by default.

Answer the question at the end by quoting:

Giuliani was born in an Italian-American enclave in East Flatbush in the New York City borough of Brooklyn, the only child of working-class parents, Harold Angelo Giuliani (1908-1981) and Helen Giuliani (nee D'Avanzo; 1909-2002), both children of Italian immigrants. Giuliani is of Tuscan origins from his father side, as his paternal grandparents (Rodolfo and Evangelina Giuliani) were born in Montecatini, Tuscany, Italy. He was raised a Roman Catholic. Harold Giuliani, a plumber and a bartender, had trouble holding a job, and was convicted of felony assault and robbery, serving time in Sing Sing.
Several of Giuliani's appointees to head City agencies became defendants in criminal proceedings. In 2000, Giuliani appointed 34-year-old Russell Harding, the son of Liberal Party of New York leader and longtime Giuliani mentor Raymond Harding, to head the New York City Housing Development Corporation, although Harding had neither a college degree nor relevant experience. In 2005, Harding pleaded guilty to defrauding the Housing Development Corporation and to possession of child pornography. He was sentenced to five years in prison. Russell Harding committed suicide in 2012. In a related matter, Richard Roberts, appointed by Giuliani as Housing Commissioner and as chairman of the Health and Hospitals Corporation, pleaded guilty to perjury after lying to a grand jury about a car that Harding bought for him with City funds. Giuliani was a longtime backer of Bernard Kerik, who started out as a NYPD detective driving for Giuliani's campaign. Giuliani appointed him as the Commissioner of the Department of Correction and then as the Police Commissioner. Giuliani was also the godfather to Kerik's two youngest children. After Giuliani left office, Kerik was subject to state and federal investigations resulting in his pleading guilty in 2006, in a Bronx Supreme Court, to two unrelated ethics violations. Kerik was ordered to pay $221,000 in fines. Kerik then pleaded guilty in 2009, in a New York district court, to eight federal charges, including tax fraud and false statements, and on February 18, 2010, he was sentenced to four years in federal prison. Giuliani was not implicated in any of the proceedings.

What did he plead guilty to?
to two unrelated ethics violations.
