Tuhia tētahi tohutoro mō tēnei wāhanga - I mua, i te wā hoki o te Pakanga ā-Iwi, he kāwanatanga wehewehe a Pennsylvania. Ahakoa kua whakakorehia e Pennsylvania te mahi pononga, he maha nga Pennsylvanians manawanui e whakapono ana kaore te kawanatanga o te kawanatanga e uru ki te umanga pononga. Ko tētahi o aua tangata ko te Democrat James Buchanan, te perehitini whakamutunga i mua i te Pakanga o mua. I wikitoria te rōpū a Buchanan i ngā pōtitanga perehitini me ngā pōtitanga kāwana i Pennsylvania. Heoi, ko te hui tuatahi o te Pāti Reipa hou
i tū ki Philadelphia, ā, i ngā pōtitanga o te tau 1860 i toa ai te Pāti Reipa i te pōti perehitini o te kāwanatanga me te tari kāwana. Whai muri i te hinganga o te Crittenden Compromise, te wehenga o te Tonga, me te Pakanga o Fort Sumter, ka tiimata te Pakanga a-Rohe me Pennsylvania hei mema matua o te Uniana. Ahakoa te wikitoria a te Republican i te pōtitanga o te tau 1860, i kaha tonu te mana o te Manapori i te kawanatanga, a he maha nga "kopere" i karanga mo te rangimarie i te wa o te pakanga. I riro anō i ngā Manapori te mana whakahaere o te whare ture o te kāwanatanga i te pōtitanga o te tau 1862, engari i mau tonu te mana whakahaere o te kāwanatanga ki te kāwana o Reipa o Andrew Curtin i te tau 1863. I te pōtitanga o te tau 1864, ka hinga a Peresideni Lincoln i a George B. McClellan no Pennsylvania mo nga pooti pooti o te kawanatanga.
