Hemispheric Latinidad describes various aspects of cultural proximity across the diverse ethnic, national, and geopolitical terrains of the Americas. The prefix “hemi,” from the Greek word meaning “half,” is joined to the Latin word “sphera,” which denotes a round, solid formation, such as a ball or globe. The planet, envisioned in terms of two halves (hemispheres) is conceived as a division of the Earth from either north to south or east to west by an imaginary line passing through the poles. As such, hemispheric Latinidad constitutes a 21st-century reconfiguration of the panethnic identity “Latino/Latina” (or Latinx) that emerged during the final quarter of the 20th century to replace the “Hispanic” designation for peoples of Latin American extraction contributing to the US national project. As a site of continual political contest (rather than a finished product), Latinidad has garnered skepticism from observers and scholars who argue that political opportunism and governmental expedience undergird attempts to consolidate Latinx subjects across divisions of race, class, gender, sexuality, nationality, migratory patterns, religion, language, and other axes of social difference to formulate a single, homogenous identity. However, contemporary scholarship that engages the conceptual framework of hemispheric Latinidad endeavors to take into account both the limitations, and the liberatory prospects, of approaches that emphasize interrelationships across Latinx and Latin American experiences. Hemispheric Latinidad hones in on the notion of overlap, as populations across the Americas contend with interlocking levels of domination that stem from the consequences of colonization, patriarchal hegemony, late capitalism, and other hemispheric structures that consolidate institutional powers and privileges along corporatist agendas. This interstitial approach to hemispheric experience informs projects of documentation, theorization, transformation, and rehabilitation of Latin American and Latinx peoples who share common experiences of national rejection within the US context, while contending with US economic, political, cultural, and military interventions and incursions into Latin American, the Caribbean, and indigenous territories in the Western Hemisphere that shape hemispheric patterns of migration, mobility, and immobility. Proponents of hemispheric Latinidad argue that these cumulative, interstitial encounters with Western domination and resistance occasion the need for conversations under an expansive rubric to describe a range of inter/intranational circumstances.
