Late in 1907 a missionary from Kisserawe in German East Africa complained of a spate of ngoma ritual dances among the Zaramo people. In particular he singled out an ngoma conducted by women to ameliorate a drought that was threatening that year's maize crop. As the women danced around a well, dressed as men and brandishing muskets, they appealed for rain from ‘their god’. Several aspects of this ngoma make it remarkable. It occurred following the Majimaji uprising in German East Africa, which the Germans put down with such violence as to make war as a tactic of resistance unpopular if not untenable. The ngoma was attended by Christian and non-Christian African women alike, suggesting a purpose whose expediency cut across competing belief systems. Finally, although cross-dressing was an aspect of certain Zaramo rituals, the symbolic appropriation of men's social roles by dress and wielding of weapons made this ngoma anomalous and suggests that the participants were consciously and purposefully reshaping gender roles at this time. The timing and symbolism of the ngoma make it clear that it was a reaction to the threat of famine, which had become a recurrent aspect of Zaramo life by 1907 and a symptom of ongoing rural social change ushered in by colonial rule. The larger question is whether changing perceptions of gender roles intersected with the Majimaji war (1905–7), and whether Majimaji had an underlying meaning for rural Tanzanian societies that has escaped the attention of historians. If so, it suggests that the prevailing conception of Majimaji needs to be questioned and re-examined.
