Between 1492 and 1504, Genoese explorer Christopher Columbus led four Spanish-based transatlantic maritime expeditions to the Americas, a continental landmasst contact, Eurasian diseases such as smallpox began to devastate the indigenous populations, which had no immunity to them. Columbus participated in the beginning of the Spanish conquest of the Native Americans, including by enslaving and brutally treating groups of them, though the exact figures and accuracy of accounts of these events are still debated, in part due to an alleged historiographical anti-Spanish and anti-Catholic disinformation campaign. Following Columbus's death, in 1507, the Americas were named after Amerigo Vespucci, who was realized that these continents were a unique landmass. The search for a westward route to Asia was completed in 1521, when the Castilian Magellan-Elcano expedition sailed across the Pacific and reached Southeast Asia, before returning to Europe and completing the first circumnavigation of the world.

Grounded theory is a systematic methodology employed in the social sciences. The methodology involves the construction of hypotheses and theories through the collecting and analysis of data. Grounded theory involves the application of a research methodology that involves inductive reasoning. The methodology contrasts with the hypothetico-deductive model used in traditional scientific research. A study based on grounded theory is likely to begin with a question, or even just with the collection of qualitative data. As researchers review the data collected, repeated ideas or concepts become apparent to the researchers. These ideas/concepts "emerge" from the data. The researchers tag those ideas/concepts with codes that succinctly summarize the ideas/concepts. As more data are collected, and re-reviewed, codes can be grouped into concepts, and then into categories. These categories may become the basis of a hypothesis or a new theory. Thus, grounded theory is quite different from the traditional scientific model of research, where the researcher chooses an existing theoretical framework, develops one or more hypotheses derived from that framework, and only then collects data for the purpose of assessing the validity of the hypotheses.
