The Federalist Papers. Beginning on October 27, 1787 the Federalist Papers were first published in the New York press under the signature of "Publius". These papers are generally considered to be one of the most important contributions to political thought made in America.
It was a trigger that showed that there were two competing powers in Europe: Russia and Austria-Hungary (and their allies).
Franz Ferdinand was killed by a Serbian separatist and the Austrians wanted to see him punished. On the other hand, Russia supported Serbia is saying that Austrian demands ( to be allowed to search for the culprit inside Serbia) were too much.

Jim Crow Laws was state and local laws enacted in the United States that institutionalized racial segregation, affecting African Americans, Asians, and other ethnic groups. Effective between 1876 and 1965. A "Jim Crow epoch" or a "Jim Crow era" refers to the time when this practice occurs. Major laws require that public schools and most public places (including trains and buses) have separate facilities for whites and blacks. These Jim Crow Laws were distinct from the Black Codes (1800-1866), which restricted African American civil liberties and rights.
Examples of restrictions placed on studies with animal participation include: setting a cap on the amount of time the animal can “work”, provide realistic temporary home environments, ensuring consistent nourishment in the form of food and water on a time scale, allowance for social interaction with other animals, ensuring the experience is harmless, and following regulations set by the Animal Welfare Act (ACA)/ People for the Ethical Treatment of Animals (PETA)/ or another animal care and safety organization.
These restriction examples can help to ensure the health, happiness, and safety of participating animals.
