[Q]: what is the last time period mentioned?, Context: From the 1987 season until the late 1990s, the most exposure the league would receive was on ESPN, which aired tape-delayed games, often well after midnight, and often edited to match the alloted time slot. The league received its first taste of wide exposure in 1998, when Arena Bowl XII was televised nationally as part of ABC's old Wide World of Sports.
[A]: 1998


[Q]: Raiders can also be called?, Context: Perhaps the most famous raid by Oeselian pirates occurred in 1187, with the attack on the Swedish town of Sigtuna by Finnic raiders from Couronia and Oesel. Among the casualties of this raid was the Swedish archbishop Johannes. The city remained occupied for some time, contributing to its decline as a center of commerce in the 13th century and the rise of Uppsala, Visby, Kalmar and Stockholm. The Livonian Chronicle describes the Oeselians as using two kinds of ships, the piratica and the liburna. The former was a warship, the latter mainly a merchant ship. A piratica could carry approximately 30 men and had a high prow shaped like a dragon or a snakehead and a rectangular sail. Viking-age treasures from Estonia mostly contain silver coins and bars. Saaremaa has the richest finds of Viking treasures after Gotland in Sweden. This strongly suggests that Estonia was an important transit country during the Viking era.
[A]: pirates
