Abraham Lincoln (lahir di Hardin County, Kentucky, 12 Februari 1809 – meninggal di Washington, D.C., 15 April 1865 pada umur 56 tahun) adalah Presiden Amerika Serikat yang ke-16, menjabat sejak 4 Maret 1861 hingga terjadi pembunuhannya. Dia memimpin bangsanya keluar dari Perang Saudara Amerika, mempertahankan persatuan bangsa, dan menghapuskan perbudakan. Namun, saat perang telah mendekati akhir, dia menjadi presiden AS pertama yang dibunuh. Sebelum pelantikannya pada tahun 1860 sebagai presiden pertama dari Partai Republik, Lincoln berprofesi sebagai pengacara, anggota legislatif Illinois, anggota DPR Amerika Serikat, dan dua kali gagal dalam pemilihan anggota senat.

Sebagai penentang perbudakan, Lincoln memenangkan pencalonan presiden Amerika Serikat dari Partai Republik pada tahun 1860 dan kemudian terpilih sebagai presiden. Masa pemerintahannya diwarnai dengan kekalahan dari pihak Negara Konfederasi Amerika, yang pro perbudakan, dalam Perang Saudara Amerika. Dia mengeluarkan dekrit yang memerintahkan penghapusan perbudakan melalui Proclamation of Emancipation pada tahun 1863, dan menambahkan Pasal ketiga belas ke dalam UUD AS pada tahun 1865.

Lincoln mengawasi perang secara ketat, termasuk pemilihan panglima perang seperti Ulysses S. Grant. Para ahli sejarah menyimpulkan bahwa Lincoln mengorganisir faksi-faksi dalam Partai Republik dengan baik, membawa tiap pemimpin faksi ke dalam kabinetnya dan memaksa mereka bekerja sama. Lincoln berhasil meredakan ketegangan dengan Inggris menyusul Skandal Trent pada tahun 1861. Di bawah kepemimpinannya pihak Utara berhasil menduduki wilayah Selatan dari awal peperangan. Lincoln kemudian terpilih kembali sebagai presiden AS pada tahun 1864.

Para penentang perang mengkritisi Lincoln karena sikapnya yang menolak berkompromi terhadap perbudakan. Sebaliknya, kaum konservatif dari golongan Republikan Radikal, faksi pro penghapusan perbudakan Partai Republik, mengkritisi Lincoln karena sikapnya yang lambat dalam penghapusan perbudakan. Walaupun terhambat oleh berbagai rintangan, Lincoln berhasil menyatukan opini publik melalui retorika dan pidatonya; pidato terbaiknya adalah Pidato Gettysburg. Mendekati akhir peperangan, Lincoln bersikap moderat terhadap rekonstruksi, yaitu mendambakan persatuan kembali bangsa melalui kebijakan rekonsiliasi yang lunak. Penggantinya, Andrew johnson, juga mendambakan persatuan kembali orang kulit putih, tapi gagal mempertahankan hak para budak yang baru dibebaskan. Lincoln dinilai sebagai presiden AS yang paling hebat sepanjang sejarah Amerika.

“He was a secretive man, who kept his own counsel. He was an ambitious man of humble origins, with colossal designs on the future. And it would always be advantageous not to be closely known, never to be transparent. Passing a farmer on a day, he would tip his hat and grin. Everybody knew him. Nobody knew him. He would play the fool, the clown, the melancholy poet dying for love, the bumpkin. He would take the world by stealth and not by storm. He would disarm enemies by his apparent naiveté, by seeming pleasantly harmless. He would go to such lengths in making fun of his own appearance that others felt obliged to defend it. -Daniel Mark Epstein.” Abraham Lincoln

“Let every American, every lover of liberty, every well wisher to his posterity, swear by the blood of the Revolution, never to violate in the least particular, the laws of the country; and never to tolerate their violation by others.” Abraham Lincoln
