A secular state is a concept of secularism, whereby a state or country purports to be officially neutral in matters of religion, supporting neither religion nor irreligion. A secular state also claims to treat all its citizens equally regardless of religion, and claims to avoid preferential treatment for a citizen from a particular religion/nonreligion over other religions/nonreligion. Secular states do not have a state religion or equivalent, although the absence of a state religion does not guarantee that a state is secular. In addition, secular states are not necessarily communist nations enforcing state atheism on the population by way of religious censorship and persecution.

Secular states become secular either upon establishment of the state (e.g. United States of America or India) or upon secularization of the state (e.g. France or Nepal). Movements for laïcité in France and for the separation of church and state in the United States defined modern concepts of secularism. Historically, the process of secularising states typically involves granting religious freedom, disestablishing state religions, stopping public funds to be used for a religion, freeing the legal system from religious control, freeing up the education system, tolerating citizens who change religion or abstain from religion, and allowing political leadership to come to power regardless of religious beliefs.

Michael Nugent (born 1 June 1961) is an Irish writer and activist. He has written three books, co-written two and was one of the three writers of comedy musical play I, Keano. He has campaigned on many political issues, often with his late wife Anne Holliday, and he is chairperson of the advocacy group Atheist Ireland. He argues that atheism provides a better model of reality, and a better basis for morality, than believing in gods; that atheists can enjoy the benefits that many people get from religion, without the harmful effects; and that the state should be secular, promoting neither religion nor atheism. He writes a blog about happiness and atheism, and he supports Bohemians and Leeds United football clubs.

Nugent was completing a project on the Gospels in primary school when he started to question the “comic book” nature of the Bible. He attended St. Aidan's C.B.S. secondary school in Whitehall in Dublin. He graduated in visual communications in 1983 at the College of Marketing and Design, now part of the Dublin Institute of Technology. He has since addressed graduate events at both institutions. In 1983, he was elected president of the college students' union and students' representative on the Dublin City Council Vocational Education Committee. In 1984, he was defeated when he ran for the post of education officer in the Union of Students in Ireland, in opposition to Joe Duffy, then USI president, who is now a broadcaster with RTE. He then took a course in product development, and set up as a freelance designer.
