In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

The following is a list of marsupials which have been taxonomically described in the 2000s.
Species of the infraclass Marsupialia of mammals discovered and described in the 2000s.
In 2002 it was discovered that the originally named mountain brush-tailed possum of Australia actually consists of two separate species. Due to taxonomic rules, the northern population has been renamed with the common name short-eared possum but will keep the scientific name Trichosurus caninus, while the southern population has been named with the common and scientific names mountain brush-tailed possum (Trichosurus cunninghami). This is because the original type specimen of the species was from the northern population, and therefore must keep the original scientific name.[1]

The following is a list of marsupials which have been taxonomically described in the 2000s. Species of the infraclass Marsupialia of mammals discovered and described in the 2000s.
Mammals are divided into two subclasses based on reproductive techniques: egg laying mammals (the monotremes), and live birth mammals. The second subclass is divided into two infraclasses: pouched mammals (the marsupials) and placental mammals. Australia is home to two of the five extant species of monotremes and the majority of the world's marsupials (the remainder are from Papua New Guinea, eastern Indonesia, Timor-Leste and the Americas). The taxonomy is somewhat fluid; this list generally follows Menkhorst and Knight and Van Dyck and Strahan, with some input from the global list, which is derived from Gardner and Groves. This is a sub-list of the list of mammals of Australia. Conservation status listed follows the IUCN Red List of Threatened Species (v. 2013.2; data current at 5 March 2014): EX - extinct EW - extinct in the wild CR - critically endangered EN - endangered VU - vulnerable NT - near threatened LC - least concern DD - data deficient NE - not evaluated
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including kangaroos, koalas, opossums, possums, Tasmanian devils, wombats, wallabies, and bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to placentals. The evolutionary split between placentals and marsupials occurred 125–160 million years ago in the Middle Jurassic–Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian continent, including mainland Australia, Tasmania, New Guinea, and nearby islands. The remaining 30% are distributed across the Americas, primarily in South America, with thirteen species in Central America and a single species, the Virginia opossum, inhabiting North America north of Mexico. Marsupial sizes range from a few grams in the long-tailed planigale, to several tons in the extinct Diprotodon. The word marsupial comes from marsupium, the technical term for the abdominal pouch. It, in turn, is borrowed from the Latin marsupium and ultimately from the ancient Greek μάρσιππος (mársippos), meaning 'pouch'.
Opossums () are members of the marsupial order Didelphimorphia () endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 126 species in 18 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America in the late Cenozoic. The Virginia opossum is the only species found in the United States and Canada. It is often simply referred to as an opossum; in North America, it is commonly referred to as a possum (; sometimes rendered as 'possum in written form to indicate the dropped "o"). The Australasian arboreal marsupials of suborder Phalangeriformes are also called possums because of their resemblance to opossums, but they belong to a different order. The opossum is typically a nonaggressive animal and does not often transmit rabies.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
