A literary review lays the track that Duvalier later rides

La Revue Indigene: Les Arts et la Vie began publishing in 1927 and became the organ of Haiti's Indigenous Movement. Its writers held that Haitian art should be drawn from African and Creole sources instead of copied from European ones. The setting sharpened the claim. Marines held the ports, the roads and the national finances, so a magazine asserting that Haitians alone would define what Haiti was doing amounted to claiming the one territory the occupation had not garrisoned. That claim had a long afterlife. Out of indigenism came noirisme, the doctrine that political power in Haiti properly belonged to the black majority rather than to the light-skinned families who had held it since 1804. It supplied the vocabulary of Haitian politics for the next three decades. Francois Duvalier came up inside it as an ethnologist, and once in office he turned the argument about African inheritance into a licence for permanent personal rule. Ideas made by poets in a small magazine are not safe from the people who inherit them.

The New York Stock Exchange estimated in 1929 that twenty million Americans owned stock, and Frederick Lewis Allen used that figure in the popular history he published in 1931. It was wildly wrong. The chief actuary of the Treasury calculated that about three million Americans, under two and a half per cent of the population, held securities in 1928, and brokerage firms reported 1,548,707 customers in 1929. Pension funds did not yet exist to give workers an indirect stake. So the crash by itself did almost nothing to the finances of the ordinary American, who owned nothing to lose. Stock prices recovered about a fifth of their losses by April 1930 and no major bank or company had failed. Kennedy's point is that the crash and the depression are two different events, and that the most careful students of 1929 have never demonstrated a causal link running from one to the other.

Between the wars a class of educated Africans in the French territories began arguing about politics in print, and the administration worried that they would find a rural following. Tiemoko Garan Kouyate, an activist and for a time a communist, wrote about the emerging African proletariat and about nationalism. He belonged to a set of men across French western and equatorial Africa who ran newspapers, built the first trade unions and corresponded with Marcus Garvey and with George Padmore, the Trinidadian who took charge of the African section of the Comintern in 1927. Plenty of African politicians in these years worked with the colonial order. Blaise Diagne, elected to the French assembly from Senegal in 1914 on rural votes, made himself an ally of France and defended its policies in public, conscription included. Andre Matswa built a society in the French Congo in the late 1920s demanding French citizenship and the rights attached to it, and by the early 1930s the administration had broken both him and it. Dockers struck at Conakry in 1919 and railwaymen in 1925 and 1938.

Haitian men avoided the main roads to escape the labour draft. Women could not, because they were the market sellers, the caregivers, the landowners, the shopkeepers and the domestic servants whose work required travel. American records and Marine photograph albums are full of pictures captioned as the typical country woman on a burro. Some men used that familiarity for cover. The Caco general Theophil toured the north recruiting while dressed as a market woman, travelling with a burro. General Petit Severe, wanted by the authorities in Cap-Haïtien, came and went from the town as he pleased in the same disguise, moving seven burro loads of rifles across the Dominican border. The performance made attacks on American officers possible. Visibility cut the other way as well, and girls and women travelled in groups for safety. Madame Benoît, wife of the Caco leader, went regularly to Mirebalais, Lascahobas and Port-au-Prince for supplies in the company of other market women, riding a bay mule and carrying a revolver under her dress.
