The Moche developed in the north coastal valleys of Peru between 200 and 850 ad. These societies evolved from earlier regional civilizations like Cupisnique and Gallinazo thanks, in part, to their advances in irrigation agriculture and the extension of fields into the deserts, which permitted population increases never seen before in the Andean region of South America. The Moche were never organized as a single, centralized polity but rather constituted multiple interacting medium- and small-scale regional societies, possibly complex chiefdoms and early forms of archaeological states, with two large regional divisions in the northern and southern valleys. Due to their fragmentary nature, there were more aspects that were differences between these societies than those aspects that were common. They seem to have spoken two different languages, Muchik in the north and Quignam in the south. Religions and ritual practices; a shared pantheon of divinities; and mythical narratives expressed in their iconography and performed in monumental structures, locally called huacas, were shared among Moche polities. It is hypothesized that Moche elites were also moving between polities, due to marriage and political alliance. The Moche excelled in multiple crafts, particularly metallurgy and ceramics, and were responsible for the development of multiple technological innovations. During most of their history, the Moche were isolated from other Andean societies, interacting only between themselves. This isolation was permitted by a specialization in the agriculture of the coastal valleys and in the exploitation of marine resources. Between 800 and 850, and due to external and internal causes, the Moche polities experienced different processes of rapid decline that led to the formation of a new generation of civilizations, the Lambayeque in the northern region, and the Chimú in the southern.

At least four major periods help to understand Brazilian history from pre-contact until modern times: the era of indigenous societies prior to 1500; the Portuguese colonial period (1500–1808); the experience of the Monarchy (1808–1889); and the Republic (1889–2019). Although the expanding and varied repositories offering digital resources do not necessarily cover these four highlighted periods thoroughly, researchers should still know them before navigating through the documents and images such repositories are making freely available to the public. Historical Brazilian digital holdings can be grouped into nine broad areas: (1) documents produced by national, state, and municipal governments; (2) records relating to specific historical moments; (3) sources for immigrant, indigenous, and African and Afro-Brazilian studies; (4) collections helpful for examining labor, industry, and plantations; (5) sources relevant for sex and gender studies; (6) materials for the history of science; (7) personal and private collections; (8) periodicals (newspapers and magazines); (9) and sources related to artistic, patrimonial, and cultural production. Researchers will find abundant sources about Brazilian society, political changes, the economy, education, commercial relations, wars and revolts, urban reforms, companies, violence, customs, and values, among many other topics and issues. Scholars and students can access interviews, photographs, newspapers, magazines, books, civil and parish records, laws and reports from government institutions, correspondence, music, movies, documentaries, maps, and much more.
