"In 1801, President Jefferson aptly described the new settler-state's intentions for horizontal and vertical continental expansion, stating: "However our present interests may restrain us within our own limits, it is impossible not to look forward to distant times, when our rapid multiplication will expand itself beyond those limits and cover the whole northern, if not the southern continent, with a people speaking the same language, governed in similar form by similar laws." This vision of manifest destiny found form a few years later in the Monroe Doctrine, signaling the intention of annexing or dominating former Spanish colonial territories in the Americas and the Pacific, which would be put into practice during the rest of the century."
