Question: When did the state where Michael Schwerner died become a right to work state?

full_context: Document 1: List of U.S. state birds: Below is a list of U.S. state birds as designated by each state's legislature. The selection of state birds began in 1927, when the legislatures for Alabama, Florida, Maine, Missouri, Oregon, Texas and Wyoming selected their state birds. The last state to choose its bird was Arizona in 1973. Alaska, California, and South Dakota permit hunting of their state birds. Pennsylvania has adopted a ``state game bird ''but not a state bird, while Alabama, Georgia, Massachusetts, Missouri, Oklahoma, South Carolina, and Tennessee have designated an additional`` state game bird'' for the purpose of hunting. The northern cardinal is the state bird of seven states, followed by the western meadowlark as the state bird of six states. Several states have extinct official animals, such as state dinosaurs in addition to state insects, state butterflies, state mammals and state reptiles.
Document 2: To Kill a Mockingbird: Scholar Patrick Chura, who suggests Emmett Till was a model for Tom Robinson, enumerates the injustices endured by the fictional Tom that Till also faced. Chura notes the icon of the black rapist causing harm to the representation of the "mythologized vulnerable and sacred Southern womanhood". Any transgressions by black males that merely hinted at sexual contact with white females during the time the novel was set often resulted in a punishment of death for the accused. Tom Robinson's trial was juried by poor white farmers who convicted him despite overwhelming evidence of his innocence, as more educated and moderate white townspeople supported the jury's decision. Furthermore, the victim of racial injustice in To Kill a Mockingbird was physically impaired, which made him unable to commit the act he was accused of, but also crippled him in other ways. Roslyn Siegel includes Tom Robinson as an example of the recurring motif among white Southern writers of the black man as "stupid, pathetic, defenseless, and dependent upon the fair dealing of the whites, rather than his own intelligence to save him". Although Tom is spared from being lynched, he is killed with excessive violence during an attempted escape from prison, shot seventeen times.

The author of the resolution stated that a constituent researched the Oklahoma Constitution and found no "official" vote regarding "Labor Omnia Vincit", therefore opening the door for an entirely new motto.

Document 6: The Death of Emmett Till: "The Death of Emmett Till", also known as "The Ballad of Emmett Till", is a song by American musician and Nobel Laureate Bob Dylan about the murder of Emmett Till.

Document 7: Separation of church and state in the United States: The "religious test" clause has been interpreted to cover both elected officials and appointed ones, career civil servants as well as political appointees. Religious beliefs or the lack of them have therefore not been permissible tests or qualifications with regard to federal employees since the ratification of the Constitution. Seven states, however, have language included in their Bill of Rights, Declaration of Rights, or in the body of their constitutions that require state office-holders to have particular religious beliefs, though some of these have been successfully challenged in court. These states are Texas, Massachusetts, Maryland, North Carolina, Pennsylvania, South Carolina, and Tennessee.
Document 8: Civil rights movement: SNCC had undertaken an ambitious voter registration program in Selma, Alabama, in 1963, but by 1965 little headway had been made in the face of opposition from Selma's sheriff, Jim Clark. After local residents asked the SCLC for assistance, King came to Selma to lead several marches, at which he was arrested along with 250 other demonstrators. The marchers continued to meet violent resistance from police. Jimmie Lee Jackson, a resident of nearby Marion, was killed by police at a later march in February 17, 1965. Jackson's death prompted James Bevel, director of the Selma Movement, to initiate and organize a plan to march from Selma to Montgomery, the state capital.
Document 9: Admission to the Union: The Admission to the Union Clause of the United States Constitution, oftentimes called the New States Clause, and found at Article IV, Section 3, Clause 1, authorizes the Congress to admit new states into the United States beyond the thirteen already in existence at the time the Constitution went into effect.
Document 10: Murder in Mississippi: Murder in Mississippi is a 1990 television film which dramatized the last weeks of civil rights activists Michael "Mickey" Schwerner, Andrew Goodman and James Chaney, and the events leading up to their disappearance and subsequent murder during Freedom Summer in 1964.

Document 11: Incorporation of the Bill of Rights: Incorporation, in U.S. law, is the process by which American courts have applied portions of the U.S. Bill of Rights to the states. When it was first ratified, the Bill of Rights only protected the rights it enumerated from federal infringement, allowing states and local governments to abridge them. However, beginning in 1897 with Chicago, Burlington and Quincy Railroad v. City of Chicago, various portions have been held to be incorporated against state and local government through the Fourteenth Amendment.

Document 13: To Kill a Mockingbird: The origin of Tom Robinson is less clear, although many have speculated that his character was inspired by several models. When Lee was 10 years old, a white woman near Monroeville accused a black man named Walter Lett of raping her. The story and the trial were covered by her father's newspaper which reported that Lett was convicted and sentenced to death. After a series of letters appeared claiming Lett had been falsely accused, his sentence was commuted to life in prison. He died there of tuberculosis in 1937. Scholars believe that Robinson's difficulties reflect the notorious case of the Scottsboro Boys, in which nine black men were convicted of raping two white women on negligible evidence. However, in 2005, Lee stated that she had in mind something less sensational, although the Scottsboro case served "the same purpose" to display Southern prejudices. Emmett Till, a black teenager who was murdered for flirting with a white woman in Mississippi in 1955, and whose death is credited as a catalyst for the Civil Rights Movement, is also considered a model for Tom Robinson.

Document 15: State constitution (United States): Usually, they are much longer than the United States Constitution, which only contains 4,543 words. State constitutions are usually longer than 8,500 - words because they are more detailed regarding the day - to - day relationships between government and the people. The shortest is the Constitution of Vermont, adopted in 1793 and currently 8,295 words long. The longest is Alabama's sixth and current constitution, ratified in 1901, about 345,000 words long. Both the federal and state constitutions are organic texts: they are the fundamental blueprints for the legal and political organizations of the United States and the states, respectively.
