^The 2nd Seanad Éireann was actually the first Seanad elected under the 1937 constitution. This is because the Free State Seanad was considered to be in continuous session, since it members were elected for a period of nine years (reduced in 1928 from the original 12 years), with elections every three years for a those senators whose terms had expired. The Free State Seanad is therefore collectively known as the First Seanad.
