<translate> The efforts to standardise Kiswahili were driven by missionary groups. On one hand, German missionaries who were keen on using the dialects from Mombasa Kenya, Pate Kenya and Tanga Tanzania, which are areas where they were stationed. On the other hand, English missionaries were keen on using Kiunguja because it was the language where they were stationed, in Zanzibar and neighbouring islands, and therefore the languagedialect they were most familiar with. In 1930 the Inter-territorial Language Committee chose the Zanzibari Kiswahili dialect, Kiunguja, as the source of Standard Kiswahili, a decision influenced by British colonial rule over East African territories. <swh>Juhudi za kusanifisha Kiswahili ziliendeshwa na makundi ya kimishonari. Kwa upande mmoja, wamishonari Wajerumani ambao walikuwa na hamu ya kutumia lahaja kutoka Mombasa Kenya, Pate Kenya na Tanga Tanzania, ambayo ni maeneo waliyokuwa wamekita kambi. Kwa upande mwingine, wamishonari wa Waingereza walikuwa na hamu ya kutumia Kiunguja kwa sababu ndiyo lugha iliyokuwa ikitumika walikokita kambi - Zanzibar na visiwa vya jirani, na kwa hiyo lughalahaja hii ilikuwa ile waliyoifahamu zaidi. Mnamo mwaka wa 1930, Kamati ya Kimaeneo ya Lugha ilichagua lahaja ya Kiswahili ya Kizanzibari, Kiunguja, kuwa chimbuko la Kiswahili Sanifu, uamuzi ulioshawishiwa na utawala wa kikoloni wa Waingereza katika maeneo ya Afrika Mashariki.
