the emancipation of black women. With this in mind she had, in 1955, embarked on an illegal journey to Lausanne, Switzerland, in order to participate in the World Congress of Mothers held by the Women's International Democratic Federation (WIDF). Accompanied by her fellow activist Dora Tamana, and as an official delegate of FEDSAW, she embarked on a journey that would see an attempt to stow away on a boat leaving Cape Town under "white names", defy (with the help of a sympathetic pilot) segregated seating on a plane bound for London and gain entry to Britain under the pretext of completing her course in Bible studies. She would visit England, Germany, Switzerland, Romania, China and Russia, meeting women leaders often engaged in left-wing politics, before arriving back in South Africa a wanted woman. Ngoyi was known as a strong orator and a fiery inspiration to many of her colleagues in the ANC. She was among the 156 Treason Trialists arrested in December 1956, and was finally acquitted of the charges against her in 1960. She was rearrested more than once in the early 1960s, and spent 71 days in solitary confinement in 1963. Ngoyi spent a total of 15 years living under three five-year banning orders, which included restrictions that confined her to her home in Orlando, Soweto, and prevented her from meeting any other banned persons. Additional conditions of the banning orders included being forbidden to attend public gatherings, make speeches or be quoted; even at her own home, she was not permitted to be with more than one person at the same time. The first two banning orders were imposed in 1962 and 1967, and when the second banning order expired in 1972, she was able to meet colleagues and friends again, and travelled to Durban and Cape Town. In 1975, a banning order against her was imposed again; however, this time its conditions did allow her some communication with the outside world. Memorials and honours The Koos Beukes Clinic at the Chris Hani Baragwanath Hospital in Soweto has been renamed Lilian Ngoyi Community Clinic in her honour. On 16 November 2004, the South African Ministry of the Environment launched the lead ship in a class of environmental patrol vessels named in her honour. On 9 August 2006, the 50th anniversary of the march on Pretoria, Strijdom Square from which the women marched was renamed Lilian Ngoyi Square.
