Answer by taking a quote from the following article:

Muhammad Yunus (Bengali: muhaammd iunuus; born 28 June 1940) is a Bangladeshi social entrepreneur, banker, economist, and civil society leader who was awarded the Nobel Peace Prize for founding the Grameen Bank and pioneering the concepts of microcredit and microfinance. These loans are given to entrepreneurs too poor to qualify for traditional bank loans. In 2006, Yunus and the Grameen Bank were jointly awarded the Nobel Peace Prize "for their efforts through microcredit to create economic and social development from below". The Norwegian Nobel Committee said that "lasting peace cannot be achieved unless large population groups find ways in which to break out of poverty" and that "across cultures and civilizations, Yunus and Grameen Bank have shown that even the poorest of the poor can work to bring about their own development".

In early 2006 Yunus, along with other members of the civil society including Professor Rehman Sobhan, Justice Muhammad Habibur Rahman, Dr Kamal Hossain, Matiur Rahman, Mahfuz Anam and Debapriya Bhattacharya, participated in a campaign for honest and clean candidates in national elections. He considered entering politics in the later part of that year. On 11 February 2007, Yunus wrote an open letter, published in the Bangladeshi newspaper Daily Star, where he asked citizens for views on his plan to float a political party to establish political goodwill, proper leadership and good governance. In the letter, he called on everyone to briefly outline how he should go about the task and how they can contribute to it. Yunus finally announced that he is willing to launch a political party tentatively called Citizens' Power (Nagorik Shakti) on 18 February 2007. There was speculation that the army supported a move by Yunus into politics. On 3 May, however, Yunus declared that he had decided to abandon his political plans following a meeting with the head of the interim government, Fakhruddin Ahmed. In July 2007 in Johannesburg, South Africa, Nelson Mandela, Graca Machel and Desmond Tutu convened a group of world leaders "to contribute their wisdom, independent leadership and integrity to tackle some of the world's toughest problems." Nelson Mandela announced the formation of this new group, The Elders, in a speech he delivered on the occasion of his 89th birthday. Yunus attended the launch of the group and was one of its founding members. He stepped down as an Elder in September 2009, stating that he was unable to do justice to his membership due to the demands of his work. Yunus is a member of the Africa Progress Panel (APP), a group of ten distinguished individuals who advocate at the highest levels for equitable and sustainable development in Africa. Every year, the Panel releases a report, the Africa Progress Report, that outlines an issue of immediate importance to the continent and suggests a set of associated policies. In July 2009, Yunus became a member of the SNV Netherlands Development Organisation International Advisory Board to support the organisation's poverty reduction work. Since 2010, Yunus has served as a Commissioner for the Broadband Commission for Digital Development, a UN initiative which seeks to use broadband internet services to accelerate social and economic development. In March 2016, he was appointed by United Nations Secretary-General Ban Ki-moon to the High-Level Commission on Health Employment and Economic Growth, which was co-chaired by presidents Francois Hollande of France and Jacob Zuma of South Africa.

How did they try to achieve that?
