Many of the writers in the Tanzimat period wrote in several different genres simultaneously: for instance, the poet Namik Kemal also wrote the important 1876 novel İntibâh ("Awakening"), while the journalist İbrahim Şinasi is noted for writing, in 1860, the first modern Turkish play, the one-act comedy "Şair Evlenmesi" ("The Poet's Marriage"). An earlier play, a farce entitled "Vakâyi'-i 'Acibe ve Havâdis-i Garibe-yi Kefşger Ahmed" ("The Strange Events and Bizarre Occurrences of the Cobbler Ahmed"), dates from the beginning of the 19th century, but there remains some doubt about its authenticity. In a similar vein, the novelist Ahmed Midhat Efendi wrote important novels in each of the major movements: Romanticism (Hasan Mellâh yâhud Sırr İçinde Esrâr, 1873; "Hasan the Sailor, or The Mystery Within the Mystery"), Realism (Henüz On Yedi Yaşında, 1881; "Just Seventeen Years Old"), and Naturalism (Müşâhedât, 1891; "Observations"). This diversity was, in part, due to the Tanzimat writers' wish to disseminate as much of the new literature as possible, in the hopes that it would contribute to a revitalization of Ottoman social structures.
