Abortion
History and religion

Since ancient times, abortions have been done using a number of methods, including herbal medicines acting as abortifacients, sharp tools through the use of force, or through other traditional medicine methods. Induced abortion has a long history and can be traced back to civilizations as varied as ancient China (abortifacient knowledge is often attributed to the mythological ruler Shennong), ancient India since its Vedic age, ancient Egypt with its Ebers Papyrus (c. 1550 BCE), and the Roman Empire in the time of Juvenal (c. 200 CE). One of the earliest known artistic representations of abortion is in a bas relief at Angkor Wat (c. 1150). Found in a series of friezes that represent judgment after death in Hindu and Buddhist culture, it depicts the technique of abdominal abortion.

In Judaism (Genesis2:7), the fetus is not considered to have a human soul until it is safely outside of the woman, is viable, and has taken its first breath. The fetus is considered valuable property of the woman and not a human life while in the womb (Exodus 21:22-23). While Judaism encourages people to be fruitful and multiply by having children, abortion is allowed and is deemed necessary when a pregnant woman's life is in danger. Several religions, including Judaism, which disagree that human life begins at conception, support the legality of abortion on religious freedom grounds. In Islam, abortion is traditionally permitted until a point in time when Muslims believe the soul enters the fetus, considered by various theologians to be at conception, 40 days after conception, 120 days after conception, or at quickening. Abortion is largely heavily restricted or forbidden in areas of high Islamic faith such as the Middle East and North Africa.

Some medical scholars and abortion opponents have suggested that the Hippocratic Oath forbade physicians in Ancient Greece from performing abortions; other scholars disagree with this interpretation, and state that the medical texts of Hippocratic Corpus contain descriptions of abortive techniques right alongside the Oath. The physician Scribonius Largus wrote in 43 CE that the Hippocratic Oath prohibits abortion, as did Soranus of Ephesus, although apparently not all doctors adhered to it strictly at the time. According to Soranus' 1st or 2nd century CE work Gynaecology, one party of medical practitioners banished all abortives as required by the Hippocratic Oath; the other party to which he belonged was willing to prescribe abortions only for the sake of the mother's health. In Politics (350 BCE), Aristotle condemned infanticide as a means of population control. He preferred abortion in such cases, with the restriction that it "must be practised on it before it has developed sensation and life; for the line between lawful and unlawful abortion will be marked by the fact of having sensation and being alive."

In the Catholic Church, opinion was divided on how serious abortion was in comparison with such acts as contraception, oral sex, and sex in marriage for pleasure rather than procreation. The Catholic Church did not begin vigorously opposing abortion until the 19th century. As early as ~100 CE, the Didache taught that abortion was sinful. Several historians argue that prior to the 19th century most Catholic authors did not regard termination of pregnancy before quickening or ensoulment as an abortion. Among these authors were the Doctors of the Church, such as St. Augustine, St. Thomas Aquinas, and St. Alphonsus Liguori. In 1588, Pope Sixtus V (r. 1585–1590) was the only Pope before Pope Pius IX (in his 1869 bull, Apostolicae Sedis) to institute a Church policy labeling all abortion as homicide and condemning abortion regardless of the stage of pregnancy. Sixtus V's pronouncement was reversed in 1591 by Pope Gregory XIV. In the recodification of 1917 Code of Canon Law, Apostolicae Sedis was strengthened, in part to remove a possible reading that excluded excommunication of the mother. Statements made in the Catechism of the Catholic Church, the codified summary of the Church's teachings, considers abortion from the moment of conception as homicide and called for the end of legal abortion.

Denominations that support abortion rights with some limits include the United Methodist Church, Episcopal Church, Evangelical Lutheran Church in America and Presbyterian Church USA. A 2014 Guttmacher survey of abortion patients in the United States found that many reported a religious affiliation: 24% were Catholic while 30% were Protestant. A 1995 survey reported that Catholic women are as likely as the general population to terminate a pregnancy, Protestants are less likely to do so, and evangelical Christians are the least likely to do so. A 2019 Pew Research Center study found that most Christian denominations were against overturning Roe v. Wade, which in the United States legalized abortion, at around 70%, except White Evangelicals at 35%.

Abortion has been a fairly common practice, and was not always illegal or controversial until the 19th century. Under common law, including early English common law dating back to Edward Coke in 1648, abortion was generally permitted before quickening (14–26 weeks after conception, or between the fourth and sixth month), and at women's discretion; it was whether abortion was performed after quickening that determined if it was a crime. In Europe and North America, abortion techniques advanced starting in the 17th century; the conservatism of most in the medical profession with regards to sexual matters prevented the wide expansion of abortion techniques. Other medical practitioners in addition to some physicians advertised their services, and they were not widely regulated until the 19th century when the practice, sometimes called restellism, was banned in both the United States and the United Kingdom.

Some 19th-century physicians, one of the most famous and consequential being the American Horatio Storer, argued for anti-abortion laws on racist and misogynist as well as moral grounds. Church groups were also highly influential in anti-abortion movements, and religious groups more so since the 20th century. Some of the early anti-abortion laws punished only the doctor or abortionist, and while women could be criminally tried for a self-induced abortion, they were rarely prosecuted in general. In the United States, some argued that abortion was more dangerous than childbirth until about 1930 when incremental improvements in abortion procedures relative to childbirth made abortion safer. Others maintain that in the 19th century early abortions under the hygienic conditions in which midwives usually worked were relatively safe. Several scholars argue that, despite improved medical procedures, the period from the 1930s until the 1970s saw more zealous enforcement of anti-abortion laws, alongside an increasing control of abortion providers by organized crime.

In 1920, Soviet Russia became the first country to legalize abortion after Lenin insisted that no woman be forced to give birth. Iceland (1935) and Sweden (1938) would follow suit to legalize certain or all forms of abortion. In Nazi Germany (1935), a law permitted abortions for those deemed "hereditarily ill", while women considered of German stock were specifically prohibited from having abortions. Beginning in the second half of the 20th century, abortion was legalized in a greater number of countries. In Japan, abortion was first legalized by the 1948 "Eugenics Protection Law" meant to prevent the births of "inferior" humans. As of 2022, due to Japan's continuing strongly patriarchal culture and traditional views on women's societal roles, women who want an abortion must normally get written permission from their partner.
