The Handbook of Texas describes a $1936$ Texas constitutional amendment mandating unequal apportionment by limiting the number of state representatives from the most populous Texas counties $($i$.$e$.$ the ones with large cities$).$ This would have later been held to be unconstitutional due to a later U$.$S$.$ Supreme Court decision that created the legal principle of:

"separate but equal is inherently unequal"

"one person one vote"

"the personal is political"

"separate but equal"

$"$no justice no peace"
