Spanish Second Republic Parliamentary Cosponsorship Networks, 1931-1939

Afinidades Elegidas provides the parliamentary co-authorship network of the Spanish Second Republic from 1931 to 1939. The dataset connects 1,026 deputies across three legislatures via 63,508 co-authoring pairs derived from 94,621 records of jointly signed legislative measures. Rodrigo Rodrigues-Silveira and the Luz y Taquígrafos project produced this first systematic reconstruction, which includes network metrics and political metadata.

Use Cases

• Analyze political alliances and faction behavior based on co-sponsorship network edges and weights.
• Study the evolution of legislative collaboration across three constitutional legislatures from 1931 to 1939.
• Calculate social network metrics like centralities and structural roles for historical deputies.
• Model inter-party proximity and aggregate party statistics from the derived matrices.

Strengths

• Contains 94,621 individual co-authorship records, providing a detailed activity log.
• Covers 1,026 unique deputies and 63,508 co-authoring pairs, offering substantial network scale.
• Includes derived social network analysis metrics like centralities, behavioral profiles, and a six-category structural role taxonomy.
• Is the first systematic reconstruction of legislative collaboration networks for this historical period.
