scar Arnulfo Romero y Galdmez (15 August 1917 24 March 1980) was a prelate of the Catholic Church in El Salvador. He served as Auxiliary Bishop of the Archdiocese of San Salvador, the Titular Bishop of Tambeae, as Bishop of Santiago de Mara, and finally as the fourth Archbishop of San Salvador. As archbishop, Romero spoke out against social injustice and violence amid the escalating conflict between the military government and left-wing insurgents that led to the Salvadoran Civil War. In 1980, Romero was shot by an assassin while celebrating Mass. Though no one was ever convicted for the crime, investigations by the UN-created Truth Commission for El Salvador concluded that Major Roberto D'Aubuisson, a death squad leader and later founder of the right-wing Nationalist Republican Alliance (ARENA) political party, had ordered the killing.In 1997, Pope John Paul II bestowed upon Romero the title of Servant of God, and a cause for his beatification was opened by the church. The cause stalled, but was reopened by Pope Benedict XVI in 2012. Romero was declared a martyr by Pope Francis on 3 February 2015, paving the way for his beatification on 23 May 2015. During Romero's beatification, Pope Francis declared that his "ministry was distinguished by his particular attention to the most poor and marginalized." Pope Francis canonized Romero on 14 October 2018.

Seen as a social conservative at the time of his appointment as archbishop in 1977, Romero was deeply affected by the murder of his friend and fellow priest Rutilio Grande and thereafter became an outspoken critic of the military government of El Salvador. Hailed by supporters of liberation theology, Romero, according to his biographer, "was not interested in liberation theology" but faithfully adhered to Catholic teachings on liberation and a preferential option for the poor, desiring a social revolution based on interior reform. Up to the end of his life, his spiritual life drew much from the spirituality of Opus Dei.In 2010, the United Nations General Assembly proclaimed 24 March as the "International Day for the Right to the Truth Concerning Gross Human Rights Violations and for the Dignity of Victims" in recognition of the Romero's role in defense of human rights. Romero actively denounced violations of the human rights of the most vulnerable people and defended the principles of protecting lives, promoting human dignity and opposing all forms of violence. Archbishop Jos Luis Escobar Alas, one of Romero's successors as Metropolitan Archbishop of the Roman Catholic Archdiocese of San Salvador, El Salvador, asked Pope Francis to proclaim Romero a Doctor of the Church, which is an acknowledgement from the church that his religious teachings were orthodox and had a significant impact on its philosophy and theology.Latin American church groups often proclaim Romero an unofficial patron saint of the Americas and El Salvador; Catholics in El Salvador often refer to him as San Romero, as well as Monseor Romero. Outside of Catholicism, Romero is honored by other Christian denominations, including the Church of England and Anglican Communion, through the Calendar in Common Worship, as well as in at least one Lutheran liturgical calendar. Romero is also one of the ten 20th-century martyrs depicted in statues above the Great West Door of Westminster Abbey in London.

El Salvador ( (listen); Spanish: [el salβaˈðoɾ] (listen), meaning "The Saviour"), officially the Republic of El Salvador (Spanish: República de El Salvador), is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2021 is estimated to be 6.8 million.Among the Mesoamerican nations that historically controlled the region are the Lenca (after 600 AD), the Mayans, and then the Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However the Viceroyalty of Mexico had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemala by the Spanish, which included the territory that would become El Salvador until its independence from Spain in 1821. It was forcefully incorporated into the First Mexican Empire, then seceded, joining the Federal Republic of Central America in 1823. When the federation dissolved in 1841, El Salvador became a sovereign state, then formed a short-lived union with Honduras and Nicaragua called the Greater Republic of Central America, which lasted from 1895 to 1898.From the late 19th to the mid-20th century, El Salvador endured chronic political and economic instability characterized by coups, revolts, and a succession of authoritarian rulers. Persistent socioeconomic inequality and civil unrest culminated in the Salvadoran Civil War from 1979 to 1992, fought between the military-led government backed by the United States, and a coalition of left-wing guerrilla groups. The conflict ended with the Chapultepec Peace Accords. This negotiated settlement established a multiparty constitutional republic, which remains in place to this day.

While this Civil War was going on in the country large numbers of Salvadorans emigrated to the United States, and by 2008 they were one of the largest immigrant groups in the US.El Salvador's economy has historically been dominated by agriculture, beginning with the Spanish taking control of the indigenous cacao crop in the 16th century, with production centered in Izalco, and the use of balsam from the ranges of La Libertad and Ahuachapan. This was followed by a boom in use of the indigo plant (añil in Spanish) in the 19th century, mainly for its use as a dye. Thereafter the focus shifted to coffee, which by the early 20th century accounted for 90% of export earnings. El Salvador has since reduced its dependence on coffee and embarked on diversifying its economy by opening up trade and financial links and expanding the manufacturing sector. The colón, the currency of El Salvador since 1892, was replaced by the United States dollar in 2001.El Salvador ranks 124th among 189 countries in the Human Development Index. In addition to high rates of poverty and gang-related violent crime, El Salvador has the second-highest level of income inequality in Latin America. Among 77 countries included in a 2021 study, El Salvador was one of the least complex economies for doing business.
