Question: The Boston Martyrs were executed for disobeying a law banning them from where?

Context paragraphs:
Mary Dyer: Mary Dyer, born Marie Barrett (c. 1611 – 1 June 1660), was an English and colonial American Puritan turned Quaker who was hanged in Boston, Massachusetts Bay Colony, for repeatedly defying a Puritan law banning Quakers from the colony.  She is one of the four executed Quakers known as the Boston martyrs.

California foie gras law: The California foie gras law, California S.B. 1520, is a California State statute that prohibits the "force feed[ing of] a bird for the purpose of enlarging the bird's liver beyond normal size" (California Health and Safety Code § 25981) as well as the sale of products that are a result of this process (§ 25982).  This outlawed the traditional method of producing foie gras in California.  The law was enacted in 2004 and went into effect on July 1, 2012.  On January 7, 2015, U.S. District Judge Stephen V. Wilson held that the portion of California's law banning the sale of foie gras within the state (California Health and Safety Code § 25982) was preempted by the federal Poultry Products Inspection Act, and enjoined the California Attorney General from enforcing it.  That decision was overturned on appeal on September 15, 2017.

Estelle Griswold: Estelle Naomi Trebert Griswold (June 8, 1900 – August 13, 1981) was a civil rights activist and feminist most commonly known as a defendant in what became the Supreme Court case "Griswold v. Connecticut", in which contraception for married couples was legalized in the state of Connecticut, setting the precedent of the right to privacy.  Griswold served as the Executive Director of Planned Parenthood in New Haven when she and Yale professor C. Lee Buxton opened a birth control clinic in New Haven in an attempt to change the Connecticut law banning contraception.  Their actions set into motion legislation that resulted in both "Poe v. Ullman" and "Griswold v. Connecticut."

LGBT rights in Texas: Lesbian, gay, bisexual, and transgender (LGBT) people in Texas face legal challenges and discrimination not faced by other people.  The state denied gays and lesbians the right to marry a same-sex partner both by statute and in its constitution.  On June 26, 2015, the Supreme Court of the United States ruled bans on same-sex marriage to be unconstitutional in "Obergefell v. Hodges", yet the ruling remains challenged in Texas.  Texas has a hate crimes statute that strengthens penalties for certain crimes motivated by a victim's sexual orientation, although it has never been invoked.  Gender identity is not included in the hate crimes law.  There is no statewide law banning anti-LGBT discrimination, however, some localities in Texas have ordinances that in theory provide a variety of legal protections and benefits to LGBT people but aren't enforced.

Kseniya Ryzhova: Ryzhova made headlines after winning gold in the 4 × 400 metres relay at the 2013 World Championships in Athletics, and thereafter kissing her Russian teammates as they received medals on the podium.  On 18 August 2013 SkyNews reported the photo of the kiss between Ryzhova and Yuliya Gushchina as a political gesture but later retracted and said that there was a "huge debate on Twitter and other media about whether it was in protest at the government's anti-gay law"—a law banning "homosexual propaganda" in Russia.

Swiss referendums, 1978: Fourteen referendums were held in Switzerland in 1978.  The first four were held on 26 February on a popular initiative "for more co-decisions of the Federal Assembly and the People on national road making" (rejected), an amendment to the federal law on aged and bereaved insurance (approved), a popular initiative to lower the retirement age (rejected) and amending the article on the economic cycle in the Swiss Federal Constitution (approved).  The next five referendums were held on 28 May on a law on time (rejected), an amendment to the tariff law (approved), a new federal law banning abortion (rejected), a federal law on promoting research and universities (rejected) and a popular initiative "for 12 Sundays a year free from motor vehicles" (rejected).

Martyrs of Córdoba: The Martyrs of Córdoba were forty-eight Christian martyrs who were executed under the rule of Muslim conquerors in what is now southern Spain.  At the time the area was known as Al-Andalus.  The hagiography describes in detail the executions of the martyrs for capital violations of Muslim law, including apostasy and blasphemy.  The martyrdoms related by Eulogius (the only contemporary source) took place between 851 and 859.

Rugård witch trials: The Rugård witch trials took place at Rugård manor, and the community of Ebeltoft close to it, on Jylland in Denmark in 1685–1686.  It was the most significant witch trial in Denmark since the Rosborg witch trials of 1639, and caused a wave of new witch trials on Jylland after a period of diminishing witch hunts.  The case led to the issue of a new law banning local courts from handing down and enacting death sentences without confirmation of the national high court, a law which interrupted the local witch hunt and eventually stopped it nationwide.

Brown v. Entertainment Merchants Ass'n: Brown v. Entertainment Merchants Association, 564 U.S. 786 (2011), is a landmark case by the Supreme Court of the United States that struck down a 2005 California law banning the sale of certain violent video games to children without parental supervision.  In a 7–2 decision, the Court upheld the lower court decisions and nullified the law, ruling that video games were protected speech under the First Amendment as other forms of media.

Boston martyrs: The Boston martyrs is the name given in Quaker tradition to the three English members of the Society of Friends, Marmaduke Stephenson, William Robinson and Mary Dyer, and to the Friend William Leddra of Barbados, who were condemned to death and executed by public hanging for their religious beliefs under the legislature of the Massachusetts Bay Colony in 1659, 1660 and 1661.  Several other Friends lay under sentence of death at Boston in the same period, but had their punishments commuted to that of being whipped out of the colony from town to town.
